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 of Genesis and its record of only one man and woman at the beginning of history. Defenders of the gospel must be able to show that all human beings are descendants of one man and one woman (Adam and Eve) because only descendants of Adam and Eve can be saved. Thus, believers need to be able to account for Cain’s wife and show clearly she was a descendant of Adam and Eve.
In order to answer this question of where Cain got his wife, we first need to cover some background information concerning the meaning of the gospel.
