Question: “Hello, I’m a hardcore Evolution believer. I’m always telling my friends who are religious, that perhaps the Bible is just another story like King Arthur and the Knights of the Round Table… Even though I make some good points, in my opinion, against creationism, they still do not agree with me. That’s okay, but there is always one question that always seems to stump them… ‘If Adam and Eve were the first people on this planet, then how did the population become what it is without incest? Doesn't the Bible state that incest is bad…?’” Sincerely, Yoendry.
We don't even know her name, yet she was discussed at the Scopes trial, mentioned in the play and movie “Inherit the Wind” and the book and movie “Contact,” and has been talked about in countries all over the world. Is she the most-talked-about wife in history?
Skeptics have used Cain’s wife time and again to try to discredit the Book of Genesis as a true historical record. Sadly, most Christians have not been able to give an adequate answer to this question. As a result, the world thinks Christians cannot defend the authority of Scripture and, thus, the Christian faith.
For instance, at the historic Scopes trial in Tennessee in 1925, William Jennings Bryan, the prosecutor who stood for the Christian faith, failed to answer the question about Cain’s wife posed by the outspokenly anti-Christian ACLU lawyer Clarence Darrow.
The world's press was focused on this trial, and what they heard has affected Christianity to this day—Christians are seen as unable to defend the biblical record. And skeptics then make the logically fallacious jump of concluding that the biblical record is indefensible!
Sagan cleverly used common questions—such as “Who was Cain’s wife?”—questions that are often directed at Christians in an attempt to prove the Bible cannot be defended.
Sadly, most Christians probably could not answer these questions! And yet, there are answers. But, since most churches are lacking in the teaching of apologetics, particularly in regard to the Book of Genesis, most believers in the church are not “ready always to give an answer to everyone who asks you a reason for the hope in you” (1 Peter 3:15).
Why is it important?
Many skeptics have claimed that, for Cain to find a wife, there must have been other “races” of people on the Earth who were not descendants of Adam and Eve. To many people, this question is a stumbling block to accepting the creation account in Genesis and its record of only one man and woman at the beginning of history—a record on which many Old and New Testament doctrines depend.
Defenders of the gospel must be able to show that all human beings are descendants of one man and one woman (Adam and Eve)—as only those people who are descendants of Adam and Eve can be saved. Thus, believers need to be able to account for Cain’s wife and show clearly that she was a descendant of Adam and Eve. (The relevant Bible passage is Genesis 4:1-5:5.)
Before we answer this question, we will first show how important it is to the meaning of the gospel.
The first man
The Bible makes it clear that only the descendants of Adam can be saved. Romans 5 teaches that we sin because Adam sinned. The death penalty, which Adam received as judgment for his sin of rebellion, also passed on to all his descendants.
Since Adam was the head of the human race when he “fell,” we who were in the loins of Adam “fell,” also. Thus, we are all separated from God. The final consequence of sin would be separation from God in our sinful state forever. However, the good news is that there is a way for us to return to God!
Because a man brought sin and death into the world, all the descendants of Adam need a sinless Man to pay the penalty for sin and the resulting judgment of death. However, the Bible teaches that “all have sinned” (Romans 3:23). What is the solution?
The Last Adam
God provided the solution—a way to deliver man from his wretched state. Paul explains in 1 Corinthians 15 that God provided another Adam! The Son of God took on a human nature in addition to His full divinity, becoming a perfect God-man—Jesus Christ. In His humanity, He was a descendant of Adam (through Noah, Abraham and David)—He thus became our relation! He is called “the last Adam” (1 Corinthians 15:45), because he took the place of the first Adam. He became the new head, and, because he was sinless, He was able to pay the penalty for sin:
Christ suffered death (the penalty for sin) on the cross, shedding his blood (“without shedding of blood is no remission” Hebrews 9:22) so that those who repent of their sin of rebellion and put their trust in His work on the cross can be reconciled to God.
Since the Bible describes all human beings as sinners, except the God-Man Jesus, and we are all related (“And He has made all nations of men of one blood to dwell on all the face of the Earth” Acts 17:26), the gospel makes sense only on the basis that all humans alive and all who have ever lived are descendants of the first man Adam. If this were not so, then the gospel could not be explained or defended.
The first woman
Eve was made from Adam’s rib (or side) (Genesis 2:21-24)—this was a unique event. Jesus (Matthew 19:4-6) and Paul (Ephesians 5:31) use this historical and one-time event as the doctrinal foundation for the marriage of one man to one woman.
If Christians cannot defend that all humans (including Cain’s wife) can trace their ancestry ultimately to Adam and Eve, then how can they understand and explain the gospel? How can they justify sending missionaries to every tribe and nation? Therefore, one needs to be able to answer the question about Cain’s wife, to illustrate that Christians can defend the gospel and all that it teaches.
Cain's brothers and sisters
Cain was the first child of Adam and Eve recorded in Scripture (Genesis 4:1). His brothers, Abel (Genesis 4:2) and Seth (Genesis 4:25), were part of the first generation of children ever born on this Earth.
Even though only these three males are mentioned by name, Adam and Eve had other children. In Genesis 5:4 a statement sums up the life of Adam and Eve—“And the days of Adam after he had fathered Seth were eight hundred years. And he fathered sons and daughters.” This does not say when they were born. Many could have been born in the 130 years (Genesis 5:3) before Seth was born.
During their lives, Adam and Eve had a number of male and female children. The Jewish historian Josephus wrote that, “The number of Adam’s children, as says the old tradition, was thirty-three sons and twenty-three daughters.”
The Bible does not tell us how many children were born to Adam and Eve. However, considering their long life spans (Adam lived for 930 years—Genesis 5:5), it would seem reasonable to suggest there were many! Remember, They were commanded to “Be fruitful, and multiply” (Genesis 1:28).
If we now work totally from Scripture, without any personal prejudices or other extra-biblical ideas, then back at the beginning, when there was only the first generation, brothers would have had to have married sisters or there would be no more generations!
But what about God's Laws?
Many people immediately reject the conclusion that Adam and Eve’s sons and daughters married each other by appealing to the law against brother-sister intermarriage. Some say that you cannot marry your relation. Actually, if you don't marry your relation, you don't marry a human! A wife is related to her husband even before they marry because all people are descendants of Adam and Eve—all are of “one blood.” The law forbidding marriage between close relatives was not given until the time of Moses (Leviticus 18-20). Provided marriage was one man to one woman for life (based on Genesis 1 and 2), there was no disobedience to God’s law originally when close relatives (even brothers and sisters) married each other.
Remember that Abraham married his half-sister (Genesis 20:12). God blessed this union to produce the Hebrew people through Isaac and Jacob. It was not until some 400 years later that God gave Moses laws that forbade such marriages.
Today, brothers and sisters (and half-brothers and half-sisters, etc.) are not permitted by law to marry because their children have an unacceptably high risk of being deformed. The more closely the parents are related, the more likely it is that any offspring will be deformed.
There is a very sound genetic reason for such laws that is easy to understand. Every person has two sets of genes, there being some 130,000 pairs that specify how a person is put together and functions. Each person inherits one gene of each pair from each parent. Unfortunately, genes today contain many mistakes (because of sin and the Curse), and these mistakes show up in a variety of ways. For instance, some people let their hair grow over their ears to hide the fact that one ear is lower than the other—or perhaps someone's nose is not quite in the middle of his or her face, or someone's jaw is a little out of shape—and so on. Let's face it, the main reason we call each other normal is because of our common agreement to do so!
The more distantly related parents are, the more likely it is that they will have different mistakes in their genes. Children, inheriting one set of genes from each parent, are likely to end up with pairs of genes containing a maximum of one bad gene in each pair. The good gene tends to override the bad so that a deformity (a serious one, anyway) does not occur. Instead of having totally deformed ears, for instance, a person may only have crooked ones! (Overall, though, the human race is slowly degenerating as mistakes accumulate, generation after generation.)
However, the more closely related two people are, the more likely it is that they will have similar mistakes in their genes, since these have been inherited from the same parents. Therefore, a brother and a sister are more likely to have similar mistakes in their genes. A child of a union between such siblings could inherit the same bad gene on the same gene pair from both, resulting in two bad copies of the gene and serious defects.
Adam and Eve did not have accumulated genetic mistakes. When the first two people were created, they were physically perfect. Everything God made was “very good” (Genesis 1:31), so their genes were perfect—no mistakes! But, when sin entered the world (because of Adam—Genesis 3:6, Romans 5:12), God cursed the world so that the perfect creation then began to degenerate, that is, suffer death and decay (Romans 8:22). Over thousands of years, this degeneration has produced all sorts of genetic mistakes in living things.
Cain was in the first generation of children ever born. He (as well as his brothers and sisters) would have have received virtually no imperfect genes from Adam or Eve, since the effects of sin and the Curse would have been minimal to start with (it takes time for these copying errors to accumulate). In that situation, brother and sister could have married with God’s approval, without any potential to produce deformed offspring.
By the time of Moses (a few thousand years later), degenerative mistakes would have built up in the human race to such an extent that it was necessary for God to forbid brother-sister (and close relative) marriage (Leviticus 18-20). (Also, there were plenty of people on the Earth by then, and there was no reason for close relations to marry.)
Cain and the Land of Nod
Some claim that the passage in Genesis 4:16-17 means that Cain went to the land of Nod and found a wife. Thus, they can conclude there must have been another race of people on the Earth, who were not descendants of Adam, who produced Cain’s wife.
From what has been stated previously, it is clear that all humans, Cain’s wife included, are descendants of Adam. However, this passage does not say that Cain went to the land of Nod and found a wife. John Calvin, commenting on these verses, states:
Others have argued that because Cain built a “city” in the land of Nod, there must have been a lot of people there. However, the Hebrew word translated as “city” need not mean what we might imagine from the connotations of “city” today. The word meant a “walled town” or a protected encampment. Even a hundred people would be plenty for such a “city.” Nevertheless, there could have been many descendants of Adam on the Earth by the time of Abel's death (see below).
Who was Cain fearful of? (Genesis 4:14)
First of all, in the days before civil government was instituted to punish murderers (Genesis 9:6), someone would want to harm Cain for killing Abel only if they were closely related to Abel! Strangers could hardly have cared. So the people Cain was afraid of could not have been another race of people.
Note the phrase “in the course of time.” We know that Seth was born when Adam was 130 years old (Genesis 5:3), and Eve saw him as a “replacement” for Abel (Genesis 4:25). Therefore, the period from Cain’s birth to Abel's death may have been 100 years or more—allowing plenty of time for other children of Adam and Eve to marry and have children and grandchildren. By the time Abel was killed, there could well have been a considerable number of descendants of Adam and Eve, involving several generations.
Where did the technology come from?
Because of intense evolutionary indoctrination, many people today think that our generation is the most intelligent that has ever lived on this planet. But just because we have jet airplanes and computers, it does not mean that we are the most intelligent. Modern technology results from the accumulation of knowledge. We stand on the shoulders of those who have gone before us.
Our brains have suffered from 6,000 years of the Curse (since Adam). We are greatly degenerated compared with people many generations ago. We may now be nowhere near as intelligent or inventive as Adam and Eve’s children. Scripture gives us a glimpse of what appears to be great inventiveness from the beginning.
Many Christians cannot answer the question about Cain’s wife because they focus on today's world (and the problems associated with close relations marrying), and do not understand the clear historical record God has given to us.
They try to interpret Genesis from our present situation, rather than understand the true biblical history of the world and the changes that have occurred because of sin. Because they are not building their world view on Scripture, but taking a secular way of thinking to the Bible, they are blinded to the simple answers.
Genesis is the record of the God who was there as history happened. It is the word of One who knows everything, and who is a reliable witness from the past. Thus, when we use Genesis as a basis for understanding history, we can make sense of questions that would otherwise be a mystery.
