They had incestuous sex with Eve. But it’s generally not discussed in bible study’s.

Cain slew Abel...and then lo and behold Cain took a wife! That was it...ever since I was a child I questioned that and never got a satisfactory answer. 70 years later I’m still waiting....!

No shit don't forget the mud people who since not Jewish didn't count

Also, don't forget that Noah, the guy who was highly over imbibing after a center event, was also procreating with his daughter in-laws. Also, his sons were most likely procreating with their mother They had to get the genome project dna completely correct.

Supposedly, Cain and Able married women from the land of Nod. Ask a Christian sometime where the land of Nod was located and how it could possibly exist if Adam and Eve and their two sons were allegedly the only inhabitants of the planet. Watch their heads spin and steam come out of their ears.

The bibly says Cain left with a sister. And Seth is another son mentioned. Cain and his wife had Enoch - who never died, as he was taken up and walked with god. Enoch has two biblical books that are included in the Ethiopian bibly.

Eve was busy, I guess.

Exactly! They say the bible is absolutely true, so there must have been a lot of incest going on!

I suppose it is possible that Cain and Abel were homosexuals......
