One thing that always confused me...If Adam was 1st man...Eve came from Adam, (seeing as she came from "a rib" then that suggests she was a genetically engineered clone*) they had two sons, Cain and Abel...
Right so far?
Well...where the heck did the women that the sons married come from, and who performed the ceremony????
* God says to Adam..."You need a companion, and I am going to make you one"
Adam replies: "Cool...I want a sexy Blonde that always does as she is told, never answers back, doesn't nag, and won't spend a fortune in the shops...How much will that cost me?"
God says: "For that, it'll cost you an arm and a leg, my son!"
Adam: "OK then, what can I get for a rib?"
