There are two major views with regard to the time involved in Creation: the old-earth view and the young-earth view. The latter believes the universe is no more than approximately 15,000 years old, while the former holds that it is probably about 13.7 billion years old.

Young-earthers take the "days" of Creation to be six successive, literal, solar days of twenty-four hours each, totaling 144 hours of Creation. They also reject any significant time gaps between the accounts in Genesis 1 or within the genealogies in Genesis 5 and 11.

Not all scholars who take the days of Genesis to be twenty-four hour days are young-earthers (some hold a gap theory); however, all who hold to a young earth hold to the twenty-four-hour-day view.

There are many biblical arguments presented in favor of the twenty-four-hour-day position. We will list several of those arguments below.

In spite of the fact that many find these arguments convincing proof of six successive twenty-four-hour days of Creation, the case is less than definitive for several reasons.

Following each arguement for the twenty-four-hour-day position, we will present a response from those who reject the six-successive-solar-day view.

Argument: It is contended that the usual meaning of the Hebrew word yom ("day") is twenty-four hours unless the context indicates otherwise. The context does not indicate anything but a twenty-four-hour day in Genesis 1; hence, the days should be taken as solar days.

Response: It is true that most often the Hebrew word yom (day) means "twenty-four hours." However, this is not definitive for its meaning in Genesis 1 for several reasons.First, the meaning of the term is not determined by a majority vote but by the context in which it is used. It is not important how many times it is used elsewhere but how it is used here.Second, even in the Creation story in Genesis 1-2, "day" (yom) is used of more than a twenty-four hour period. Speaking of the whole six days of Creation Genesis 2:4 refers to it as "the day" (yom) when all things were created.Third, and finally, yom is elsewhere used of long periods of time as in Psalm 90:4, which is cited in 2 Peter 3:8: "A day is like a thousand years."

Argument: Further, it is noted that when numbers are used in a series (1, 2, 3…) in connection with the word day (yom) in the Old Testament, it always refers to twenty-four-hour days. The absence of any exception to this in the Old Testament is given as evidence of the fact that Genesis 1 is referring to twenty-four-hour days.

Response: Critics of the twenty-four-hour-day view point out that there is no rule of the Hebrew language demanding that all numbered days in a series refer to twenty-four-hour days. Further, even if there were no exceptions in the Old Testament, it would not mean that "day" in Genesis 1 does not refer to more than a twenty-four-hour period of time: Genesis 1 may be the exception! Finally, contrary to the solar-day view, there is another example in the Old Testament of a numbered series of days that are not twenty-four-hour days. Hosea 6:1-2 reads: "Come, let us return to the LORD. He has torn us to pieces but he will heal us; he has injured us but he will bind up our wounds. After two days he will revive us; on the third day he will restore us, that we may live in his presence." It is clear that the prophet is not speaking of twenty-four-hour "days," but of longer periods of time in the future. Even so, he uses numbered days in a series.

Argument: Another line of evidence is the use of the phrase "evening and morning" in connection with each day in Genesis 1. Since the literal twenty-four-hour day on the Jewish calendar began in the "evening" (by sunset) and ended in the "morning" (before sunset) the next day, it is concluded that these are literal twenty-four-hour days.

Response: First, the fact that the phrase "evening and morning" is often used in connection with twenty-four-hour days does not mean it must always be used in this way.Second, if one is going to take everything in Genesis 1 in a strictly literal way, then the phrase "evening and morning" does not encompass all of a twenty-four-hour day, but only the late afternoon of one day and the early morning of another. This is considerably less than twenty-four-hours.Third, technically, the text does not say the "day" was composed of "evening and morning" (thus allegedly making a twenty-four-hour Jewish day); rather, it simply says, "And there was evening, and there was morning–the first day" (Gen. 1:5). Further, the phrase may be a figure of speech indicating a beginning and end to a definite period of time, just as we see in phrases like "the dawn of world history" or the "sunset years of one’s life."Fourth, if every day in this series of seven is to be taken as twenty-four hours, why is the phrase "evening and morning" not used with one of the days (the seventh)? In fact, as we shall see (below), the seventh day is not twenty-four hours, and thus there is no necessity to take the other days as twenty-four hours either, since all of them alike use the same word (yom) and have a series of numbers with them.Fifth, and finally, in Daniel 8:14 "evenings and mornings" refer to a period of 2,300 days. Indeed, often in the Old Testament the phrase is used as a figure of speech meaning "continually" (cf. Ex. 18:13; 27:21; Lev. 24:3; Job 4:20).

Argument: According to the law of Moses (Ex. 20:11), the Jewish workweek (Sunday through Friday) was to be followed by a day of rest on Saturday, just as God had done on His "six-day week" of creation. The Jewish workweek refers to six successive twenty-four-hour days. This being the case, it seems that the creation week, like the workweek, was only 144 hours long.

Response: It is true that the creation week is compared with a workweek (Ex. 20:11); however, it is not uncommon in the Old Testament to make unit-to-unit comparisons rather than minute-for-minute ones. For example, God appointed forty years of wandering for forty days of disobedience (Num. 14:34). And, in Daniel 9, 490 days equals 490 years (cf. 9:24-27). What is more, we know the seventh day is more than twenty-four hours, since according to Hebrews 4 the seventh day is still going on. Genesis says that "on the seventh day [God] rested" (Gen. 2:2), but Hebrews informs us that God is still in that Sabbath rest unto which He entered after He created: "There remains, then, a Sabbath-rest for the people of God; for anyone who enters God’s rest also rests from his own work, just as God did from his" (Heb. 4:10).

Argument: Young-earthers claim that according to Genesis 1, light was not made until the fourth day (1:14), but there was life on the third day (1:11-13). However, life on earth cannot exist for millions (or even thousands) of years without light; thus, the "days" must not have been long periods of time.

Response: Light was not created on the fourth day, as defenders of the solar day argue; rather, it was made on the very first day when God said, "Let there be light" (Gen. 1:3). As to why there was light on the first day when the sun did not appear until the fourth day, there are various possibilities. Some scholars have noted a parallelism between the first three days (light, water, and land–all empty) and the second three days (light, water, and land–all filled with bodies). This may indicate a parallelism in which the first and fourth days cover the same period, in which case the sun existed from the beginning.Others have pointed out that while the sun was created on the first day, it did not appear until the fourth day. Perhaps this was due to a vapor cloud that allowed light through, but not the distinct shape of the heavenly bodies from which the light emanated.

Argument: Plants were created on the third day (1:11-13), and animals were not created until later (1:20-23). There is a symbiotic relation between plants and animals, one depending on the other for its life. For example, plants give off oxygen and take in carbon dioxide, and animals do the reverse. Therefore, plants and animals must have been created closely together, not separated by long periods of time.

Response: Some plants and animals are interdependent, but not all. Genesis does not mention all the plants and animals, but only some. If the "days" are six successive periods, then those forms of plant and animal life that need each other could have been created together. In fact, the basic order of events is the order of dependence. For instance, many plants and animals can exist without humans (and they were created first), but humans (who were created on the sixth day) cannot exist without certain plants and animals. In addition, if the "days" are parallel, then the problem does not exist, since plants and animals would exist at the same time. In any event, the argument from the symbiotic relation of plants and animals does not prove that the six "days" of Genesis 1 must be only 144 hours in duration.

Argument: It is well known that the theory of evolution (or common ancestry) depends on very long periods of time for life to develop from a one-celled animal to human beings. Without these long periods of time, evolution would not be possible. Thus, it is argued by young-earthers, that granting long periods of time is an accommodation to evolution.

Response: In response to this charge, it must be observed that allowing for long periods of time for the development of life came long before the idea of evolution. Augustine (354-430), for one, held to long periods of time for the development of life (City of God, 11.6).Also, even in modern times, scientists had concluded that long periods of time were involved before Darwin wrote in 1859.Furthermore, long periods of time do not help evolution, since without intelligent intervention, more time does not produce the specified complexity involved in life. Natural laws randomize, not specify. For example, dropping red, white, and blue bags of confetti from a plane at 1,000 feet in the air will never produce an American flag on the ground. Giving it more time to fall by dropping it at 10,000 feet will diffuse it even more.

Argument: According to this text, ‘At the beginning of creation God "made them male and female."’ If God created humankind at the beginning of Creation, then they were not created at the end of millions of years, as the old-earth view contends.

Response: First, Adam was not created at the beginning but at the end of the creation period (on the sixth day), no matter how long or short the days were.Second, the Greek word for "create" (ktisis) can and sometimes does mean "institution" or "ordinance" (cf. 1 Peter 2:13). Since Jesus is speaking of the institution of marriage in Mark 10:6, it could mean "from the beginning of the institution of marriage."Third, and finally, even if Mark 10:6 is speaking of the original creation events, it does not mean there could not have been a long period of time involved in those creative events.

Argument: According to the old-earth position, there was death before Adam. Nevertheless, the Bible declares that death came only after Adam as a result of his sin: ‘Just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned’ (Rom. 5:12; cf. 8:20-22).

Response: There are several problems with this argument.

First, Romans 5:12 does not say all animals die because of Adam’s sin, but only that "all men" die as a consequence.

Second, Romans 8 does not say that animal death results from Adam’s sin, but only that the "creation was subjected to frustration" as a result of it (v. 20).

Third, if Adam ate anything–and he had to eat in order to live–then at least plants had to die before he sinned.

Fourth, and finally, the fossil evidence indicates animal death before human death, since people are found only on the top (later) strata, while animals are found in lower (earlier) strata.

Let me insert some additional thoughts to what Dr. Geisler has written:

Romans 5:12 says, "Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned." Here we learn:

1.) Through Adam’s act of rebellion sin entered the world.

2.) Death through sin resulted—but to whom?

3.) Death spread to all men.

4.) Death spread to all men because all men sinned.

5.) Notice, it doesn’t say that death spread to all the animals—it says death spread       to all men.

6.) Further, what kind of death is the Apostle Paul talking about? Remember, the Bible describes five kinds of death:

a.) Physical death–death of the body (James 2:26)

b.) Spiritual death or separation from God (Rom. 6:23; Eph. 4:18)

c.) Eternal death–the second death (Rev. 20:14)

d.) Death to the law (Rom. 7:4)

e.) Death to sin (Rom. 6:11)

In Romans 5:12, the Apostle is primarily referring to "b"–spiritual death. Genesis 2:15-17 tells us why this is so:

God specifically told Adam and Eve on the day they would eat the forbidden fruit, "You shall surely die." Did they physically die that day? No, they did not. After they sinned, Adam and Eve were still walking around. In fact, Adam lived to be 930 years old. They tilled the ground and had children.

The death specified in Genesis 2 and 3 and by Paul in Romans 5 must be spiritual death. When Adam sinned, he instantly "died," just as God said he would. He remained alive physically, mentally, volitionally and emotionally, but he died spiritually. That is, man broke his harmonious fellowship with God and introduced the inclination or the propensity to sin (to place one’s own way above God’s). This is what is called "the Doctrine of Original Sin" (not a particular sin, but the inherent propensity to sin entered the human realm as men became sinners by nature).

In light of this:

1.) The "death through sin" Paul is talking about is not equivalent to physical death. If so, Adam and Eve would have physically died the day they ate of the tree. The Bible is talking primarily about spiritual death resulting from sin.

2.) Only humans have earned the title of "sinners." Only humans can experience "death through sin." Animals don’t sin and aren’t called sinners in the Bible. Further, animals are not offered the gift of eternal life if they repent.

3.) The death Adam experienced is carefully qualified by the Apostle Paul in Romans 5:12. He writes: "Death spread to all men"–not to all plants and animals–just on human beings.

Also, notice Romans 5:18: "Therefore, as through one man’s offense judgment came to all men, resulting in condemnation, even so through one man’s righteous act a free gift came to all men, resulting in justification of life." Here, Paul is talking about man’s fall, his spiritual dearth and separation from God and God’s salvation via Christ’s death to provide salvation to cover the sins of all men. They must receive this gift by faith in Christ.

4.) Besides spiritual death, man became mortal, liable to all the miseries of this life and cut off from the possibility of existing physically forever. In other words, as a result of the Fall, God condemned Adam to a limited life span and the certain fact of physical death in the future. God took away access to a tree in the garden that gave Adam and Eve the potential for eternal physical life. How do we know? Scripture tells us this in Genesis 3:22-24:

Apparently Adam and Eve had the potential for eternal physical life before they sinned and even afterwards. John MacArthur comments in his Study Bible regarding these verses:

Again, before the Fall God made provision for Adam and Eve to sustain their physical life forever; but after they disobeyed God, not only was there immediate spiritual death that came to them, but God pronounced a curse on them and told them they would eventually physically die by cutting them off from the tree of life.

In Genesis 3:17-19 we are told: "Then to Adam He said, ‘Because you have heeded the voice of your wife and have eaten from the tree of which I commanded you, saying, "You shall not eat of it," cursed is the ground for your sake. In toil you shall eat of it all the days of your life. Both thorns and thistles it shall bring forth for you, and you shall eat the herb of the field. In the sweat of your face ye shall eat bread till you return to the ground, for out of it you were taken, for dust you are and to dust ye shall return.’"

All Christians believe that when Adam and Eve sinned, it brought immediate spiritual death to them and the certainty of future physical death. Christians also believe that original sin came into existence at this time. Further, Christ is the only provision for man’s sinful condition. But the facts do not mandate that Christians hold plant and animal life died only after Adam and Eve sinned.

But how did the Fall affect nature? What is the meaning of Romans 8:20-22, where it states: "For the creation was subjected to frustration (futility) not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God. We know that the whole creation has been groaning as in the pains of childbirth right up till the present."

The words "futility" or "frustration" refer to the inability to achieve a goal or purpose. All creation is personified to be, as it were, longing for the transformation from the curse and its effects. Because of man’s sin God cursed the physical universe and now no part of creation entirely fulfills God’s original purpose."

Some interpret this verse to say that Adam’s sin ushered into the creation every kind of natural decay and all pain and death. They assume that the law of entropy which describes the decreasing order in the universe, did not take effect until Adam and Eve sinned. Based on this assumption, the time between the universe’s creation and Adam and Eve’s fall must be brief to explain why the physical evidence shows no period when decay and death were not in operation.

But there are several problems with this interpretation. First, if one holds to the twenty-four-hour-day hypothesis that God took six days to create everything, then according to Romans 8:22, the "whole creation" would include the universe and all the stars. But if so, did the stars not burn after the first day? Physics demands that the stars were burning and that entropy was in effect at that point. If this is the case, then decay was present from the very first day.

As Dr. Hugh Ross has written in The Genesis Question:

So, for Adam and Eve, if they did any work in the Garden, then a loss of energy and a certain amount of decay was present. Why? Because work is essential to breathing, circulating blood, contracting muscles and digesting food. These are all virtually life-sustaining processes. Adam was working, tending the Garden of Eden (Gen. 2:15) before he sinned. Thus, Romans 8:20-22 could not imply that Adam’s sin inaugurated all of the decay process.

When Paul refers to the creation "groaning," what other effects from the curse is he talking about? It could be that in Genesis 1:28 God commanded man to tend the environment, but because man sinned the environment has been ruined. The human effect on the environment is roughly analogous to the results of sending a two-year-old child to tidy up a closet. Left alone, the closet will become less tidy due to the natural tendency toward decay and disorder. Typically, though, the two-year-old will greatly speed up the decay and disorder process. Isaiah 24:5 describes the devastation of the planet that results from the insubordination of human beings to God. Just as one must wait for the two-year-old child to grow up a little before expecting him to help tidy up a closet, so too the creation waits for the human race to experience the results of God conquering the sin problem.

Even such church fathers as Origen, who lived 185 to 254 A.D., interpreted Romans 8:20-22 to imply that decay has been in effect in the natural world since the creation of the universe. Since Origen preceded by hundreds of years the scientific discovery of the laws of thermodynamics and entropy (which include the principle of decay), it is clear that he did not come up with his interpretation as a result of trying to comply with the modern scientific theories of his day.

Are there other reasons that tell us that physical pain and decay must have existed before the Fall? Yes. In Genesis 3:16 God says to Eve, "I will greatly increase [or multiply] your pains in childbearing." He does not say "introduce." He says, "Increase" or "multiply," implying there would have been some pain in any case.

As Philip Yancey has so clearly shown in his book, Where Is God When It Hurts? (Grand Rapids: Zondervan), some pain is good. It’s good that when I put my hand near fire, the pain warns me of danger. If the pain wasn’t there, I wouldn’t know that my fingers were burning. Pain is God’s way of keeping us from destroying ourselves. Adam and Eve certainly must have had the use of touch and could feel pain in the Garden before the Fall. They must have had a nervous system that protected them from any dangers in their environment in the Garden. They must have been able to feel a bee sting, or to get poison ivy, or to be pricked by a thorn. When Adam and Eve sinned, the consequences and risk of pain and decay didn’t begin, they simply increased.

While the sin we human beings commit causes us all naturally to react negatively to decay, work, physical death, pain and suffering, and while ultimately all of this is somehow tied into God’s plan to conquer sin permanently, there is nothing in Scripture that compels us to conclude that none of these entities existed before Adam’s first act of rebellion against God. On the other hand, God’s revelation through nature provides overwhelming evidence that some of these aspects did indeed exist for a long time period previous to God’s creating Adam.

Another question that arises is this. If animals died before the Fall, doesn’t this alter the biblical Doctrine of Atonement? Some cite Hebrews 9:22, which says, "In fact, the law requires that nearly everything be cleansed with blood and without the shedding of blood there is no forgiveness." They interpret this verse to say, "The basis of the gospel message is that God brought in death and bloodshed because of sin. If death and bloodshed of animals (or man) existed before Adam sinned, then the whole basis of atonement–the basis of redemption–is destroyed."

But this is faulty exegesis. While it is true there is no remission of sin without the shedding of blood, Christ’s blood, it does not necessarily follow that all shed blood is for the remission of sin. To say there could have been no bloodshed before sin is to make the same exegetical errors made by those who claim there were no rainstorms or rainbows before the Genesis Flood.

Hebrews 10:1-4 explains that the blood of animal sacrifices will not take away sin. The sacrificial killing of animals was a physical picture of the spiritual death caused by sin, which necessitated the death of a substitute to make atonement, as well as a foreshadowing of the ultimate efficacious sacrifice that God Himself would one day provide. Since the penalty for sin is spiritual death, no animal sacrifice could ever atone for sin. The crime is spiritual, thus the atonement had to be made by a spiritual Being.

The spilling of blood before Adam sinned in no way affects or detracts from the Doctrine of Atonement. Upholding that central doctrine in no way demands a creation scenario in which none of God’s creatures received a scratch or other bloodletting wound before Adam and Eve sinned. Even in an ideal natural environment, animals would be constantly scratched, pricked, bruised and even killed by accidental events and each other.
