Both accounts are consistent in one thing: universe is of finite age. There are other creation myths. I confine myself to Genesis merely because I am most familiar with it, and desire to write a pithy blog post, not a treatise.
Is a belief in a universe of finite age theologically or cosmologically necessary? Perhaps not. First the cosmology, then the theology. With references to my earlier posts on non-eternities and on different types of eternities. All of this is the work of an amateur. Read and consider at your own risk.
Entropy and Eternity
If there is some quantity in the universe, for example, entropy, that always increases as time flows, then we can infer that this rule of increase cannot always have been true from time eternal. This is a consequence of the second law of thermodynamics. If, for example, entropy has been increasing forever, then the present entropy of the universe must be infinite. Entropy cannot be infinite, because the universe has order. Therefore either eternity without Beginning exists and entropy does not always increase with time, or eternity without Beginning does not exist.
If the 2nd Law is not universally true, we may be in a linear or circular non-eternity. Due to the ultimate impossibility of distinguishing between linear and circular non-eternities, and if we are in one or the other, we cannot know which of these situations we are in. Another possibility, if the 2nd Law is not universally true, is that we exist in an open-ended linear or spiral eternity.
If the 2nd Law is universally true, we may be in a one-ended linear eternity with a rather bleak future. In that case, entropy will continue to increase until it reaches a state in which no further disorder is possible. A state of maximum disorder is not changeless in one sense, and yet is changeless in another. Maximum disorder is that state of a system, of which it can safely be assumed that all subsequent change is forever random. So its state of disorder never changes; it is changeless in one sense by remaining forever random. Yet is is always changing. On the other hand, it may be impossible for the universe to obtain perfect (infinite) disorder, even if change never ends, because, having a definite beginning, it can never become infinitely old. Instead, it may be that disorder approaches an asymptotic maximum value of disorder, while change continues to occur. Change might become progressively less interesting, as the universe ages. Time itself may slow, but never stop entirely.
However, there is evidence that the second law of thermodynamics is not universally true when gravitational force is dominant. For example, super massive objects such as black holes are believed to drop in temperature even as they absorb energy. At large scales, gravity may be the dominant universal force and may cause the second law to be violated. Therefore, entropy may be reduced continuously by "gravitational maintenance," by episodes of universal contraction, or by some other means. The point is, we really have no idea what the ultimate fate of our universe will be. For the same reason, we cannot say the the second law requires that the universe be of finite age. Perhaps it is infinitely old.
Another possibility is that eternity is, on net, timeless. Time runs forward in some parts in which entropy always increases, and backwards in other parts in which entropy always decreases. That is, time has opposite polarities, although in our part we can only experience one polarity. Wherever a forward-moving part of the universe contacts a backwards-moving part, time collapses to timelessness. Everything collapses to nothing. Time as well as space collapses. Black hole, anyone?
Space may be in essence that which allows time to separate into its constituent opposite polarities. "Nothing" is spread out into "something" by expansion of space. Light somehow breaks forth out of nothingness, and expands space. This is possible without violating conservation principles because positive expansion of space in which entropy can only increase is offset by negative expansion of space in which entropy can only decrease. On net, nothing is created. The light itself does not come out of nothing; light can be defined as that which expands space into its opposite polarities, and the capability of a collapsed nothingness to expand can be inherent in the state of nothingness. The expansion does not need to occur at a particular time; it can be always occurring, as an aspect of nothingness. In one part of the expanded space, time runs forward, and space is as we experience it. In another, corresponding part, time runs backwards and space is turned inside out. These corresponding parts are connected via one or more collapsed singularities of time and space. Matter condenses from light, and gravity appears in the expanded areas. Eventually, parts of the expanded space collapse under the influence of gravity caused by the coalescing of mass. Under this cosmological model, the cosmos is a timeless nothing that is balanced by opposing forces of expansion/light and gravity/mass. Time exists and flows only where space is expanded, in opposite polarities.
Parts of the universe where time is negative may have negative polarities of space, where light condenses not into matter, but into negative matter (not to be confused with anti-matter as understood in particle physics). The negative matter exerts a sort of negative gravity. Because the negative gravity operates within a negative space, the multiplication of negatives results in the negative gravity tending to curve or collapse space, just as gravity tends to collapse space in our positive side of the cosmos. In such a cosmos, backwards time travel for living things might not be possible without the ability to translate the stuff of life between matter and negative matter while passing through a black hole. Seems pretty tricky. But purely speculative; there is no reason to believe that negative matter is favored in zones where time is negative, other than symmetry.
Even if regular matter predominates where time is negative, whether or not life can survive a backwards flow of time is an open question. All of our metabolic functions depend on processes in which entropy, on net, increases. Every known machine constructed on our side of the universe can only operate by increase of entropy. However, it's hard to rule out the possibility of constructing a machine that tolerates a decrease in universal entropy, in operation. It might even be a trivial problem. Machines and organisms operate by offsetting a local decrease in entropy with an increase in entropy external to the machine or organism, thereby satisfying the 2nd law of thermodynamics. If 2nd law ran backwards, the machine or organism could decrease entropy without having to offset with a greater external increase. What's the problem?
The greater problem in time travel may be passing through a singularity to get to the other side. It seems doubtful that information can pass through a singularity, without being destroyed. If something can exist as anything other than undifferentiated substance while passing through a singularity, we are not talking about a singularity at all. All collections of information require space to exist, and a singularity by definition is void of space. There would have to be some other way to get to the other side, if it is possible at all. Maybe information could be transmitted to the other side through something like quantum entanglement. Perhaps there is some way to access the 5th dimension and travel to the other side without passing through a singularity. Perhaps time cannot flow backwards in any space. Who knows?
Time travel by passing into a time-space of opposite polarity faces a correspondence problem. If one enters the time-space of opposite polarity at a time and place different from the point of exit, rather destructive dislocations can occur. To think about such time travel without mind-bending dislocations, it can be assumed that opposite polarities of space-time always correspond perfectly to one another, or that dislocations in time or space do not create any serious problems. If time travel is possible by entering and re-emerging from a time-space of opposite polarity, logic requires the existence of parallel universes in both polarities.
The rendering above is intended as a conceptualization of a net-timeless eternity. It is only a rendering with artifacts having nothing intended to do with the concept, unfortunately. It does illustrate opposite polarities of space connected through a singularity, but fails to show that illustrated regions of opposite polarity are separated by a higher-order dimension. Curved 4-dimensional manifolds of space-time separated by a 5th dimension and connected through a singularity are difficult to illustrate in two dimensions. Imagine it if you can.
Theology - Abrahamic
The cosmos gets a brief mention, but the story of genesis is mainly focused on the genesis of humanity, and trying to explain what the hell went wrong. We can be pretty sure our species has not been around forever, and lived in tribal hunter-gatherer societies before the development of agriculture. Genesis can be read as expressing beliefs about evolution of human society from its hunter-gatherer origins. Older specific cosmology, (creation of the cosmos) is not a major part of the story. Except in the sense that nothing material, even the sun, moon, stars, earth, is eternal. These things once did not exist, and will one day pass away. No controversy about that. So why the controversy about Genesis? Of course, the controversy is about the nature of the Creator, or the creative force. That is the point of controversy, but it cannot be resolved scientifically.

Your Mind Is A Fractal,
its order increases with each level up.
If mind could define itself in symbols, perfectly,
the symbols would show that no limits exists
to that order increasing forever.
Transcendence is also eternal, then:
the fractal's progression can never stop.
There is no reversal or cessation.
The spirit of Christ, the anointed of the Highest,
is that which, out of love, descends from higher orders,
suffers in darkness below, unrecognized;
teaches truth without care for itself,
so freeing the damned from Hell,
which once freed, ascend to Heaven.
Ever sacrificed, and ever resurrected in glory,
so Christ permeates all of Heaven.
Heaven is a place, and a process within you:
a place of love and peaceful assurance,
a process of growing faith in one sure hope
that every apple of your eye,
and all that is worthy of love,
will endure for timeless eternity.
As it endures, transforming
all beyond imagination,
and emanating the anointed of the Most High.
Hell is a place, and a process within you:
a place of torment and fear,
a process of increasing despair and growing conviction
that every purpose of your mind and
all the desire of your heart
will perish for timeless eternity,
and is less than nothing.
Choose Heaven in your fractal
enfold the universe in life
and serve life unto death.
Choose Hell in your fractal
enfold the universe in death,
and serve death unto life.
Flee from the difficult choice
until you can hide no more;
Choose you must.

"Judgment" enables the dichotomy of good and evil, just as "sight" enables the dichotomy of light and darkness. Without judgment, there is no way to distinguish between good and evil. Without any way to make a distinction between good and evil, separate categories of good and evil cannot exist. There can be no dichotomy.
Judgment operates on intentional acts of persons. If an event is completely unintentional, it cannot be characterized as either good or evil in a moral sense. That the sun rises every 24 hours is certainly good in a practical sense, but is morally neutral unless one assumes some person (e.g., a god or the only God) causes the sun to rise every day. All of this is merely definitional; it does not need to be proven.
Who, or what, determines what is good and what is evil? A judge applying a moral rule, obviously. There are basically three types of judges: the natural or self-appointed judge, the judge voluntarily selected by parties to a dispute, and the judge who rules by force. Each person can judge their own actions and render opinions on the actions of others; these are the very numerous natural judges. Less frequently, disputes or moral questions arise for which a judge may be sought out by all the persons concerned. These are the voluntarily selected or free civil judges. Finally, there are judges that impose their opinions on persons forced to appear before them. Judgments are expressions of a judge's opinion on a law as applied to a set of facts, by definition. Discernment of good from evil is a matter of a judge's opinion on application of a moral law.
Thus, "moral law" is that rule which defines whether or not an act is good, or evil. Morality is that which a moral law defines as good. A moral person is one who does good, even when the result is not self-serving. An immoral person is one who recognizes a difference between good and evil, but does evil whenever it pleases him, or erroneously believes certain evil actions are good. An amoral person is one who does not believe that good or evil exist in any objective sense beyond the person's own opinion. Again, these are merely definitions.
People argue about whether or not good and evil can be objectively determined without presupposing that a transcendent moral reality exists. Deists may argue that absolute good and evil requires the existence of a transcendent person (i.e., God) who defines what is good, and what is evil. If we define moral judgments to be opinions, then such judgments can only be experienced by persons; thus, if such a thing as transcendent morality exists, it must do so in the mind of some transcendent being, such as a creator god (God).
Some atheists argue that morality can just exist by itself, like a law of physics, and can only be discovered by deductive reasoning. The deist who believes morality is defined by God and the moral atheist who believes in one objective morality discoverable by reason alone are indistinguishable in at least one sense. They both have faith that something greater than mere personal whim determines what is good and evil. They disagree about the nature of a transcendent reality that determines morality, and how best to discover it, but not about whether the transcendent reality exists. The agnostic straddles both of these poles, without claiming knowledge as to the exclusive truth or falsehood of either. The moral atheist, agnostic and the deist alike are faced with a very difficult problem, however: how to know what objective morality requires in any given situation. Each will use reason and rhetoric to argue for preferred moral positions, using identical tools such as appeals to authority, citation of widely accepted customs, and logic.
It may be argued that morality underlies those rules of human social behavior that enable human society (or more generally, life) to flourish in a sustainable way. This is a perfectly reasonable way to think about morality, but only if the stated goal "sustainable flourishing of ___" is accepted as the highest moral priority. Some arguments for morality based on logic presuppose that a particular social result is desirable, and work backwards to find rules of behavior that maximize the probability of achieving the desired result. The desired end result is just a matter of opinion, so such arguments lead to a type of amorality.
For example, in one person's opinion, a desirable result might be a very populous, highly technological society progressing towards interstellar travel and extended natural lifespans, with more emphasis on progress than on conservation. In another person's opinion, the desired end result may be a mostly depopulated planet with a small elite acting to restrain human population growth and maintain the planet as a sort of ecological preserve, with more emphasis on conservation than on progress; and so many different views exist. Morality in this view is a matter of personal opinion; therefore, morality is subjective and not objective. One person or group may enforce their moral preferences on others, but there is no objective difference between good and evil. Morality is merely a useful illusion projected by those having political or personal power, to legitimize power. This is the amoral viewpoint, and it is a perfectly reasonable one.
Amoral persons must struggle with finding moral purpose in anything, or living with a sense of moral futility. Some may loath to admit their amorality. Instead, it may be easier to dress amorality in garments of morality, pretend that only one acceptable outcome exists, and claim as righteousness the enforcement of one's arbitrary moral preferences as objective morality on others. Sometimes a claim of morality is hypocritically made as propaganda to deceive those who are morally obtuse. Other times, the belief is adopted willingly by the morally obtuse, as a psychological defense against feelings that their life has no meaning. By adopting a popular albeit arbitrary preference as a moral purpose, some avoid the discomfort of admitting that there is no such thing as good or evil, and therefore no moral purpose to living. Philosophically, such persons may be objective moralists led astray by an amoral shepherd. More often, followers of amoral leaders are people who have never confronted the problem of morality head on and just drift with the current, like a rudderless boat.
People who believe in objective morality face a different problem. Whether deists or atheists, these people can take comfort in a belief in objective morality. But they cannot be certain that they know what that objective morality would call for in all circumstances, or any circumstances. Sometimes, they cannot agree on what morality calls for in very basic, fundamental circumstances. Such differences are not fatal to beliefs in objective morality, because differences can be explained by human imperfection. On the other hand, many people from many different cultures, traditions, and beliefs do share similar beliefs in many basic moral precepts. This provides a sort of empirical evidence for objective morality, which many find convincing. Others may see it as just an example of convergent social evolution. Even so, if similar moral beliefs are required for long-term survival of diverse human societies, this provides a natural science basis for morality, albeit merely as a collectively-determined factor of social survival. As it is impossible to know how many diverse moral belief systems can survive in the long term, the natural science position is fundamentally amoral.
Another problem for objective moralists is ultimate judgment. If morality is objective and absolute, consequences should exist for immoral behavior. Without any consequences, the existence of morality is a cruel joke. A few may live with a firm suspicion that morality is merely a cruel joke, but others believe that consequences do exist for the evil doer. Since there are often too few consequences for evil doers evident in the natural world, some believe that supernatural consequences compensate. Beliefs in judgment after death compensate for lack of justice in the world.
If one believes in morality and judgment in whatever form such judgment exists, it follows logically that one should do as little evil as possible. This is the test of faith for believers in objective morality. If you truly believe in an effective objective morality, are you willing to set aside your natural interests when necessary to remain moral according to your deepest beliefs? Most can not, but one who truly believes in the existence of judgment would be compelled to.
On the other hand, if ultimate judgment exists, all fall short of perfection and therefore all must suffer some consequences as a result of their own moral imperfection, either naturally or supernaturally. The prospect of being judged by a law of perfect morality, or by a being of perfect morality, can be terrifying. Religions deal with this terror in different ways. For those that believe in endless cycles of reincarnation, judgment is real and terrible, but perhaps not unbearable because no worse in quality than what we experience in the natural world, and redemption is always possible after many cycles of suffering. For disbelievers in reincarnation, there are basically two alternatives for moral consequences: while alive or after death, or some combination of these.
The threat of judgment after death is not just a bludgeon of hypocrites; it is an actual, deeply rooted psychological aspect of a belief in objective morality. It can be expressed in various ways, but it comes down to the same thing: a belief that consequences of evil behavior will somehow be repaid to the evil-doer, even after death. With interest added. Otherwise, the Creator by permitting evil doers to live out their lives in comfort, and die deaths no less comfortable than those they oppress, would be manifestly unjust. But how much interest may justly be charged? And what about the role of virtues such as mercy and forgiveness?
However much is enough, imposition of eternal suffering breaks every possible moral rule, it seems. It all depends on how "suffering" is defined. Humans in a sense cause the "suffering" of livestock over countless generations, but the imposition is not (for the most part) gratuitous, and might even benefit the livestock in some respects. Contrast this to the idea of eternal hell fire. To the extent hell fire involves imposition of maximal, endless, conscious suffering on lesser beings, it cannot be moral by any conceivable measure. Any god who metes it out could not be moral by any human measure. Fire, however, signifies destruction. Destruction of irredeemably evil beings, or of evil itself, is moral, or else evil is not damnable; i.e., is not evil. So eternal hell fire understood as an eternal destruction of evil - a destructive force that prevents evil from ever emerging to exercise power over good - is the perfection of morality.
Could a moral God resurrect the damned to face judgment? An ample punishment would be to cause the evil doer to understand with no doubt, before the destruction of the soul for all eternity, that the opportunity for eternal life had been lost. The moral complaint here is a one-size-fits-all punishment. The oppressor and slayer of millions receives essentially the same punishment as a mere unrepentant sloth or drunkard (for example). Because so many die with no hope of eternal life as it is, it might seem gratuitously cruel to resurrect them solely for the purpose of saying "I told you so." There is a difference between dying without hope of eternal life for one's self by natural law, and dying with a firm regret that one could have had eternal life, if only one had done things differently. It can be questioned whether or nor it is more or less moral to inflict such sure regrets on the damned, if not for the purpose of saving their souls, or some greater good.
How can mere mortals question the morality of God? That is not the proper question. The proper question is, how can we test our own beliefs about higher objective morality against our own experience? All beliefs about untestable, transcendent realities are matters of faith, by necessity. In matters of faith, we have nothing to go on but accepting that the pattern of our own experience, understood through reason or intuition, will teach or reflect higher patterns. We will not give a scorpion to our children who ask of us an egg, nor will That Which Is Above fill us who seek truth with falsehoods. Even the acolyte who insists on blindly following words in a holy book, or the teachings of an exalted teacher, is in reality only following his own interpretation of such supposedly holy words or teachings. If such an acolyte would ascribe to God a level of cruelty that would surpass the severest discipline or torture imposed by any human, we might sensibly observe that it is the interpretation that is at fault, not the original source. The deist, like the atheist, must not ignore the light of reason. Unlike the atheist, a deist may humbly proceed on faith and intuition, where reason alone would lead to amoral or evil places. But only with the greatest humility, and not contrary to reason.
In the light of humility, questioning hypothetical scenarios such as the judgment of the damned or the eternal torture of hell fire are merely exercises in hubris and vanity. We cannot know what judgment awaits until we see it unfold. We deserve the freedom to structure our own lives in consideration of a judgment hereafter, if we so choose. We are not empowered to judge the eternal fate of our neighbors, whatever their beliefs, and especially not merely on account of their beliefs. If we would impute to our deity a cruelty surpassing even our own, or any willful arbitrary destruction, then we worship not any God, but evil spirits, the demons of our own consciousness. Conversely, we cannot presume to understand for what purpose evil exists in our world, or how it will be exorcised. It is sufficiently demanding for us to recognize our own evil conduct, and repent of it.

What is a non-eternity? For non-eternity to exist, all time everywhere and for all things that exist, have existed, or will ever exist, must have a beginning and an end. More generally speaking, the extent and influence of time must be bounded at both ends, in a non-eternity. Time bounded at only one end (for example, having a beginning but no end) might be a different type of eternity from time without beginning or end, but it is still an eternity, by definition. Supposing it is possible for time to be bounded, what are the ways in which a boundary might be imposed on it?
A non-eternity can be conceptualized as a line segment. It has a beginning and an end, and time flows from the beginning to the end. Join the opposite ends of the line segment, and you have a circle. In a circular topology of time, identical events are repeated ceaselessly. Although time in a circular flow never begins or ends, the endless perfect repetition places a boundary on time. It is therefore reasonable to label the circle a "non-eternity." In an earlier post, I referred to a "circular eternity" so and am being deliberately inconsistent with that earlier terminology here. This is merely a matter of semantics.
Upon further reflection, it is somewhat inappropriate to call a universe in which only a finite amount of change is possible an "eternity," even if endlessly repeated. On the contrary, it may be logical to define a non-eternity as a universe in which only a finite amount of change is possible. In that case we would have to be very careful about how "an amount of change" is defined, clearly, mere repetition could not increase an amount of change. On the other hand, an eternity might be defined as universe without both an end, and a beginning, of time. Under that definition, circular time might be considered an eternity; however, every moment of a circular time is both an end, and a beginning, to the rest of the time circle. So calling a time circle a non-eternity seems justifiable, under both definitions.
The analogies of a line segment and circle might be extended to additional dimensions with additional details. For example, a sphere or a toroidal helix (see illustration above) might be imagined instead of a circle. However, the topologies of a line segment or a circle represent essential ways that time can be bounded.
The Impossibility Of Distinguishing Linear and Circular Non-Eternities
If the line represents the flow of time, and time can flow only in the forward direction, the two geometries of a line segment and a circle are indistinguishable to any finite being in the continuum. In other words, a circular non-eternity and a linear non-eternity are indistinguishable to beings existing in them. Both are bounded; the linear non-eternity by a beginning and end of time, and the circular non-eternity by infinitely repeating the same sequence of events through a sort of curvature in time. Each transit of the time circle is identical to every other transit, and therefore time in a sense is continually reset or restarted. There can be no change in knowledge from one cycle to the next in a circular eternity, or else the cycles are not identical. Since there can be no change in knowledge between cycles without destroying circularity, a temporal being in a circular eternity can never know whether it is transiting an eternally repeated cycle of a time circle, or just taking a single, unique trip along a time segment. To the temporal being, each experience is and must be exactly the same.
A temporal being in a non-eternal time segment might observe an approach of the end of time. For example, it might be observed that time was gradually slowing everywhere in space, and therefore it may be anticipated that an end of time is drawing near. But the temporal being can never know whether time has ended, or is just temporarily stopped. If time stops and never restarts, the temporal being will never know. If time stops and restarts in a way that preserves at least some information through the stoppage, that is just time behaving eccentrically along its merry way. If time stops in a way that destroys all information in existence, and then restarts after all information is destroyed, no temporal being in a later cycle can recover information from the previous cycle. Such stopping and restarting may be the same, topologically speaking, as time reversing and returning everything to its original state. For the new temporal beings, time will appear to have started at the beginning of the cycle in which the beings exist.
On Different Flow Rates
It has been observed that the speed of light in a vacuum is everywhere the same regardless of the velocity or acceleration of its frame of reference. From this observation, Einstein deduced that time and space form a sort of continuum. One aspect of this continuum is that differences in the momentum history of objects can cause corresponding differences in the relative amounts of time experienced by each object. In other words, time flows at uneven rates. For example, suppose Bob stays on planet Earth, while his brother Ted accelerates away from Earth to visit Sirius, and then accelerates back from Sirius to return to Earth, before Bob dies. When Bob and Ted are reunited, they will discover that Bob has experienced more time waiting on Earth, than Ted has during his journey to Sirius and back. The logical reasons for this odd result are explained clearly here. If we accept the logical conclusion, the fact that objects in space can experience the flow of time at different rates tells us nothing obvious about the end or beginning of time itself. But it might hint at a better understanding of what time is.
Time As The Possibility Of Change
Time is, in a sense, the possibility of change. A photon emitted without any subsequent interaction with matter or energy travels at the speed of light and exists unchanged except for its position in space. It will experience neither time nor change so long as its velocity is exactly 'c'. Unless and until it interacts with the universe and changes state, time for the photon does not pass. Time nonetheless exists, in a sense, for the lonely photon so long as there is a possibility that the photon can change its state. Generally speaking the constant change in its position and the existence of the universe implies that such a possibility -- that the photon will experience time and change at some time in the future -- cannot be ruled out.
Supposing that time flows forward only and is the aspect of the universe providing the possibility of change. It follows that, even if at some time in the past the universe was not experiencing any change, the fact that it is presently experiencing change proves that it has always been possible for change to occur. Therefore time, defined as the possibility of change, has always existed.
If at some future time the entire universe ceases to experience the flow of time and reaches a state in which any further change is utterly impossible, time will have ceased to exist. In such case, time will have passed from eternal existence into oblivion. That is, time might have an end but cannot have had any beginning. It has always existed but might someday end.
The possibility of an End of Time seems unlikely, but perhaps cannot be entirely ruled out logically. Even if this strange topology (an end but no beginning) cannot be proven illogical, time will always have existed and is therefore eternal in the sense of having no beginning. Even supposing it cannot be proved that the universe will never reach a state in which all future change is impossible, logic proves that the past, future change has always been possible and therefore time (in the sense of an enabler of change) has always existed.
Although we can prove that change has always been possible, no one can prove that future change is impossible. Suppose the universe is trending towards absolute stillness, meaning the absence of all change. The trend can be observed while time and change still exist, but nothing can be observed or known once perfect stillness is achieved. Nothing whatsoever can be done. It cannot be known whether absolute stillness in the end of time is unchangeable, or merely unchanging. Unless the stillness is absolutely and necessarily permanent, then time has not ended.
Therefore if we define time as the possibility of change, non-eternity is not a logically coherent idea, because we can deduce that the possibility of change must have always existed. We can also deduce that it is unknowable whether or not time (as possibility of change) will ever end. If it is not impossible for time to have an end but no beginning, it is at the very least quite surprising. Even in that case, however, time as the possibility of change has always existed, so there can be no non-eternity.
However, this definition of time seems a bit like a rhetorical trick. If there was zero change anywhere and forever before the present epoch of change, then the universe was preceded by a changeless void, a nullity in which nothing ever existed or happened. In that case it may be more satisfying to say that time did not exist until the earliest change occurred. Perhaps time is better defined as change itself.
Time As Change Itself
If time is defined not as the possibility of change, but as change itself, we may have to wrestle with more difficult logical conundrums. This definition may require accepting that time is capable of passing into and out of existence more easily than the downstroke beat of a bee's wing. For example, if time did not exist before the earliest change, it sprang into existence with the first change. If in a trillionth to the trillionth power of a nanosecond, no change occurs anywhere in the universe, then time has flashed out of existence for that brief instant. And at countless other instants in every second of time.
If time is change itself and cannot be divided more finely than a certain amount, then time is quantized. If time is quantized, the minimum quantum of time must be non-zero, and each time quantum must be separated from its neighbors by some quantity of no-time or absolute stillness. If there is no stillness between adjacent time quanta, then time is continuous, and not quantized. Quantization by definition requires some separation between adjacent quanta, or else the quanta run into each other and cannot be distinguished from a continuum. Since change cannot occur without passage of time, this would mean that a phase of absolute stillness must, in a sense, occur between each tick of the quantum clock. Quantized time in a sense must wink in, and out, or existence between each tick. This is so, because the state of the universe must be exactly the same at the end of each time quantum as at the beginning of the next, and no change can occur except within a time quantum. So, if time is quantized, each unit of time experiences time extinction events equal in number to the unit of time divided by the time quantum.
If space has some minimum quantum while time does not, there must be some tiny slice of time over which no change within any quanta of space is possible. Within time slices that are sufficiently small, there is not enough time for particles in adjacent but different quanta of space to interact. Thus, no change can occur in countless tiny time slices of any given time interval.
Conversely, if change must occur somewhere in the universe at every instant of time no matter how finely divided, then at least one changeable quality of the universe must subsist in an infinitely divisible matrix. The only apparent candidate for such a matrix is space, alternatives such as "ether" having been shown inconsistent with experimental observations. Change cannot occur without some space for particles to evolve in. Even if it is hypothesized that a particle is a point occupying zero space, it cannot interact with anything else without some space to propagate through.
If space is infinitely divisible, every particle no matter how small encompasses an infinitely divisible volume of space, unless the particle occupies no space at all. Suppose, for example, that a "quark" is the fundamental particle. If each quark encompasses an infinitely divisible volume of space, it must either be perfectly homogenous throughout its entire volume, or have a structure that includes some smaller, more fundamental thing. If the quark must be perfectly homogenous, it encompasses a volume of space in which no change that would disrupt its internal homogeneity can occur; such that it must change instantaneously or not at all. If the quark has internal structure, either there is some smaller fundamental, necessarily homogenous thing that is too small for us to detect making it up, or there is no fundamental particle at all and every structure is infinitely complex. Some theorize that quarks encompass no space at all, and exist as "point-like" particles. Point-like particles occupy no space, and thus allow existence of arbitrarily small structures. An infinite number of points can be packed in an arbitrarily close arrangement, if there is no lower limit to the scale of space.
Thus, if space is infinitely divisible, there is no scale to the universe, which is infinitely complex and extends from from the infinitely tiny to the infinitely large. If there is no lower limit to the divisibility of space, an infinite amount of change can occur during what seems, at larger scales, to be a finite amount of time, due to this infinite complexity. Each subatomic particle can encompass a universe of smaller changes, each sub-atomic particle of that smaller universe can encompass its own universe of smaller changes, and so on up and down the scale of space. Tiny universes with tiny persons can be born, evolve, and die in the span of a heartbeat in our world -- while even tinier universes similarly pass during heartbeats of the tiny persons. Both time and space would have no discernible scale. Such a reality is not consistent with our experience, because the universe as we know it does exhibit scale. Subatomic particles exhibit different structures and behaviors than atoms, molecules, collections of atoms and molecules, cells, animals, worlds, solar systems, galaxies, and on up the scale. There do seem to be upper and lower limits to this scale. Perhaps the scale we observe in the universe is an illusion peculiar to our particular location in a sort of infinite fractal. If so, we might reasonably be deluded into believing that space and time are not infinitely divisible.
Based on observations of universal scale, but not to a logical certainty, our apparent universe includes periods of change surrounded by timeless instances of changelessness ("no-time"). If time is defined as change itself, time is continually stopping and starting. When stopped universally, time (defined as change itself) does not exist at all.
Can change occur instantaneously, therefore proving that time cannot be defined as change or the possibility of change? Logically, all change requires the passage of time. If something exists in a first state, and then changes into a second state, the question of how much time the change required is immaterial. It is sufficient that at an earlier time the thing existed in a first state, and at a later time it existed in a different state. The presence of time is needed to enable a thing to change from one state into a different state.
If a thing merely exists in two or more different states simultaneously, it is not changing. Existing in two states simultaneously does not require any time. For example, an unchanging photon may exist as both a particle and a wave without any need for time. As Relativity teaches, light can exist unchanging in no-time, such as when moving at velocity 'c' in a vacuum. It cannot be observed without interacting with something else, and thus, being changed and made subject to time. Once observed and made to experience time, it can and does change into one or the other of a particle or a wave.
Schrodinger's cat cannot really be both alive and dead at the same time, because it observes itself at some conscious or subconscious level, during macro-time. But all living things passing in and out of no-time may exist in superimposed states of life and death during those timeless leaps. Also, it may be that information can be preserved by a thing entering no-time in two or more simultaneous states. If so, it may be possible to prove that non-eternity does not exist, even in a universe with scales of space and time.
If we define time as change itself, and accept our observation that the universe has scale as valid, we can deduce that periods of change in the universe are like islands rising from an ocean of absolute stillness in which no change occurs.
We cannot deduce how our epoch will end, or whether other epochs existed prior to our own. Surmising that our own epoch is like a vast chain of islands representing change in an ocean of changelessness, we might reasonably imagine that our own "island chain" (epoch) may be separated from other epochs by an ocean of timelessness. But we will never find any evidence to support such an imagining, unless we can discover a record that can be proved to have been created in an earlier epoch.
Until then, we live in a universe of unknown age and origin, progressing towards the unknown. If time is change, non-eternity is not logically impossible, but neither is it required.

If ever love could reach across an ocean,
And back across a wide expanse of time,
Sowing seeds of hope in the driest desert --
Such love is ours, my love, your story true.
If love is just a feeling with no power
to act at all beyond our mere beliefs;
From you pours forth that power with amazement,
Your touch, your voice, your words, make me believe.
Be love what ever knows no computation,
And what ever breaks all chains of time;
O, may such love be in us ever growing,
With wonders new until our bodies rest.

Supposing there is nothing in the universe outside of time, such that everything that can exist (the "universe"), exists in time, and that time has no beginning or end, then we can make some statements about eternity. If time itself has a beginning and an end, then there is no eternity. We cannot know whether eternity exists, but if it exists we can deduce its possible structures.
We can deduce that, if eternity exists, the three possible types of generally non-random eternities are linear, circular, and spiral. We can deduce that we exist in a generally non-random universe, because we observe that the universe changes, at least some of the time, non-randomly. Each state of the universe is correlated to a prior state in a way that preserves information, for at least our epoch. So if eternity exists, it is generally non-random at least some of the time.
A linear eternity is one in which whatever has happened before, never happens again in exactly the same way. One can roll snake-eyes twice in a row, or a million times in a row, but the universe changes in countless ways between each roll of the dice. Cycles can exist, but the universe never repeats the same pattern of successive states, unless for a finite period by random happenstance. Generally, the universe never obtains exactly the same state as any prior state. However, if the universe is finite while time is infinite, it is inevitable that prior states will be replicated in the future. In a linear eternity, there is no predictable pattern to replication, if replication occurs. Occasionally, randomness or something indistinguishable from randomness must occur between successive states, breaking correlation of the state to its parent state. For example, at the instant of a big bang, randomness (or some other force, e.g., "infinite creativity" or "free will") can give rise to a new and different cycle unlike any previous cycle.
A circular eternity is one in which each state of the universe is repeated forever and ever at successive times. For example, every "big bang" is followed by a "big crunch" (or by some other destiny), after which there is a new big bang and everything that happened in the earlier universe is replicated exactly again. A never-ending series of big bangs each leading to an everlasting expansion and nested inside one another is another example of a circular eternity. This would be a structure a bit like a perpetual ripple on the surface of a pond. Whatever its structure, the characteristic feature of a circular eternity is that every state that the universe obtains is identically repeated at successive later times. There is no randomness because every state of the universe is perfectly correlated to every other state. There is no randomness, no creativity, no free will; only the pulsing of a never ending wave.
A spiral eternity is one in which states of the universe are repeated in successive cycles, but each successive cycle differs from its most recent prior counterpart in some correlated way. There is loss of information between cycles injected by forces such as randomness or free will, but not a total loss. The next cycle remains a recognizable child of its most recent parent. Like the linear eternity, there is no discernible pattern to replication (if replication occurs); like the circular eternity, successive cycles are discernibly related.
Besides linear, circular, and spiral eternities, eternity could also behave like combination of these types, for example linear sometimes, and circular or spiral sometimes, but in the ultimate analysis it must be one of these three. This conclusion follows from the starting assumptions that time has no end, time is necessary to enable change, and that at least some changes in the universe are not random. If time has a beginning but no end, then the eternities are the same as for time without beginning or end, once begun. If time has an end but no beginning, that is an impossibility. Although we can deduce the possible structures of eternity, we cannot discover empirically whether or not eternity is linear, circular, or spiral.
We (i.e., finite beings) cannot ever know by empirical science whether eternity is linear, circular, or spiral, or whether eternity exists at all. No matter how long our period of scientific observation endures, it is always finite. Therefore we can never know whether what we observe will remain so forever, or only for a temporary phase. For example, if we observe the universe expanding, we cannot know that it will never contract later on. If we see entropy always increasing, we cannot know that universal laws will not change so that entropy seems to be always decreasing during some future time.
To empirically determine the structure of eternity, it would be necessary for a part of the universe to exist outside of time, and for communication to be possible between the part of the universe subject to time, and that part outside of time. More on this in a subsequent post.
Knowledge of whether eternity exists, and if it exists is linear, circular or spiral, are rather small examples of knowledge beyond all possible reach of empirical observations. For convenience, we might refer to things that we know must be real, but cannot be known scientifically, as holy things. This is not inconsistent with the biblical meaning of "holy." In the biblical sense, holy means set apart from the mundane, empirical world.
In modern times, most people spend almost no time thinking about or discussing holy things. It feels a bit strange and useless. Many people profess the rather bleak belief that everything about our existence can be known empirically, but this belief cannot be true. There are many things that logically must be real, but cannot be known empirically. For example, we can know we exist, but we cannot know whether we exist in a time dimension that is eternal, or if eternity exists, whether its structure is linear, circular, or spiral. Although logical hypotheses about eternity are not empirically testable, they are no less logical for that. And being no less logical, they are no less possible and true.
Mathematicians have spent a great deal of time thinking about infinities, if not eternities, and practical applications have even been developed from such thinking. Mathematical infinities are not exactly the same as eternities, however. Eternities deal with the destiny of the universe, and the human race as part of that universe. Holy eternities have a special significance to ethics, because eternities enmesh related concepts like free will, predestination, and destiny, that are important in ethics. In other words, metaphysics is not entirely useless. In future posts, we will attempt to derive some use from it.

I lit a match
one bright day,
and failed to see cast light.
Its flame was feeble
in the glare,
and brought nothing to my sight.
I lit a match
one dark night,
and was astonished by its flare.
What things hidden
sprang to sight!
Never shall I despair.
