Okay ... I've gotta say it ... am I the only one who is a little weirded out about a few posters (including the OP?) who are using the adam and eve story as ... well ... seemingly a factual event that can provide us evidence for or against incest....? Like either -- adam and eve did it, so it must be acceptable --- or adam and eve did it, but their genetic line was more "pure"

so it was okay for them but not for us.
Not trying to open up a big bucket of

(I know for some posters the question of whether the adam and eve story really happened would be pretty controversial

-- to be honest the very concept that there is a "controversy" there is mind-boggling ... REALLY happened? give me a break) but really ... even aside from that "controversy", why would a bible story be appropriate to use as evidence for/against such an issue??
I had to say it ... and I did!
