"Skeptics of the Bible 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 given an adequate answer to this question. As a result, the world sees them as not being able to defend the authority of Scripture and thus the Christian faith.
If we now work totally from Scripture, without any personal prejudices or other extrabiblical ideas, then back at the beginning, when there was only the first generation, brothers would have had to marry sisters or there wouldn’t have been any more generations!.....we can say for certain that Cain’s wife was either his sister or a close relative.
A closer look at the Hebrew word for “wife” in Genesis reveals something readers may miss in translation. It was more obvious to those speaking Hebrew that Cain’s wife was likely his sister. (There is a slim possibility that she was his niece, but either way, a brother and sister would have married in the beginning.) The Hebrew word for “wife” used in Genesis 4:17 (the first mention of Cain’s wife) is ishshah, and it means “woman/wife/female.”
The word ishshah is the word for “woman,” and it means “from man.” It is a derivation of the Hebrew words ‘iysh (pronounced: eesh) and enowsh, which both mean “man.” This can be seen in Genesis 2:23 where the name “woman” (ishshah) is given to one who came from Adam.
Today, brothers and sisters (and half-brothers and half-sisters, etc.) are not currently permitted by law to marry and have children.
Now it is true that children produced in a union between brother and sister have a greater chance to be deformed. As a matter of fact, the closer the couple are in relationship, the more likely it is that any offspring will be deformed. It is very easy to understand this without going into all the technical details.
Each person inherits a set of genes from his or her mother and father. Unfortunately, genes today contain many mistakes (because of sin and the Curse), and these mistakes show up in a variety of ways.
The more closely related two people are, the more likely it is that they will have similar mistakes in their genes, inherited from the same parents. Therefore, brother and sister are likely to have similar mistakes in their genetic material. If there were to be a union between these two that produces offspring, children would inherit one set of genes from each of their parents. Because the genes probably have similar mistakes, the mistakes pair together and result in deformities in the children.
Conversely, the further away the parents are in relationship to each other, 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 some of the pairs of genes containing only one bad gene in each pair.
However, this fact of present-day life did not apply to Adam and Eve. When the first two people were created, they were perfect. Everything God made was “very good” (Genesis 1:31). That means their genes were perfect—no mistakes. But when sin entered the world because of Adam (Genesis 3:6), God cursed the world so that the perfect creation then began to degenerate, that is, suffer death and decay (Romans 8:22). Over a long period of time, this degeneration would have resulted in all sorts of mistakes occurring in the genetic material of living things." AIG

And Adam said: “This is now bone of my bones and flesh of my flesh; She shall be called Woman [ishshah], because she was taken out of Man [iysh]” (Genesis 2:23).Thus, Cain’s wife is a descendant of Adam/man. Therefore, she had to be his sister (or possibly niece). Hebrew readers should be able to make this connection easier; however, much is lost when translated.
