Do you have a question?

If it's "Where did Cain get his wife", remember that the Bible did not record every single birth and name every single child Adam and Eve had. If there was a "land of Nod", there had to have been enough time for them to "multiply" as God said when he first created them. So there is no need for a pre-Adamic race to account for this, or a "gap theory" of subhumans, or anything else.

Next time, please add comment when you cite a verse.
