 Where did Cain get his wife's questions brought up often? And the truth is that Cain got his wife either from a sister of his or from a niece. We know that this is the case because there were no other people that were created. The Bible tells us one that Eve is the mother of all those that are living specifically that day as well. And we know that when God destroyed the earth, all the people that were destroyed, including before the flood, those that died, they died as a result of sin. And sin, according to Paul in Romans five, starting in verse 12 says that sin entered the world through Adam. So these people weren't judged because of, there were some other race or someone that lived somewhere else. No, everyone who was on the earth, so everyone that was ever created was born through Adam and Eve. And though we only know of three children that are named Cain, Abel and Seth, the Bible is clear that they had many other children. And so Cain either married his sister or his niece.
