I get confused cause adam and eve had cain and able and then they were a family and so mankind came from them, right. sooooooo. Then I find out there was some daughters, and they messed around with some dudes from "the land of nod".

Like there was this WHOLE OTHER PLACE full of people that were not related to adam and eve or something. I get confused about the whole land of nod people, and progeny of mankind and adam and eve and how much incestual bangin was goin on, or IF MAYBE there were SOME OTHER "people" around to "help things along".
