I have had a rather heated argument with some fellow Fundies (from another church, not mine) over the origin of Cain's wife. (and the spouses of Noah's grandkids) They say Cain married a sister, an idea I totally reject, given GOD'S hatred of incest, calling it an abomination. (Incest is a natural taboo among peoples who've never hearda God, which is more proof of how abominable it is to Him!) GOD is NOT wishy-washy in what is sinful or abominable to Him. I don't believe He EVER condoned something He now hates so much! I argue that the BEST explanation is that GOD created more people after A&E. They argue that Scripture sez we are ALL descended from A&E. I agree, of course, but I remind them that we are each descended from ONE man and ONE woman, whom in turn are each themselves descended from ONE man and ONE woman; thus we each have FOUR grandparents, etc. etc. back thru successive generations. For example, though my surname is Roby, there are umpteen other surnames in my ancestry, but I am descended from ONE original Roby and his wife somewhere sometime. So, while A&E were the first homo sapiens created by GOD, why could He not have later created other people to be spouses for the second generation, that is, the children of A&E? Their children would still be descendants of A&E. Same goes for Noah's grandkids, excluding Nimrod who wed his own mother Semiramis. I TOTALLY reject the "incest" explanation, based upon GOD'S hatred of it, and the fact that there are five distinct races of people today, all just-as-human as the other, all just-as-eligible for salvation, but each different in appearance and physical characteristics. I am open to any other explanation that doesn't involve incest.
