Q. I was watching a pastor on a satellite channel, and he states there was a creation on earth before Genesis. He also stated that the serpent seduced Eve, and became the father of Cain. This just doesn’t pass the smell test to me. Where did this come from?
A. I don’t know who started this, but the idea of a pre-Adamic civilization is popular among some who are trying to reconcile an old Earth with a young civilization to explain the fossil record. There isn’t any Biblical basis for such a view where living beings are concerned, although I do believe that a case can be made for the Earth to be much older than the 6000 years during which it’s been populated.
As to Cain’s father being Satan, Genesis 4:1 makes it clear.
Adam lay with his wife Eve, and she became pregnant and gave birth to Cain. She said, “With the help of the LORD I have brought forth a man.”
Adam was Cain’s biological father, and Eve recognized God’s role in the procreation process.
