of course it's Adam & Eve because they've gotta have the kids ... Cain killed Abel, so I guess they are the first horrible parents of all time...Seth & the other ones...does the Holy Bible even mention that they ever had a girl? I cannot recall...from his grave, Sophocles wasn't impressed hehe.

but of course that means that we're all borne of incest but that the Old Testament leaves this out in Genesis, instead opting for the jump-cut ahead pushing the old fast-forward on the story of our origin as it were.

Basically, populations of Homo Sapiens arose in different areas of the world independently around the same generous slice of time. There is some incest, of course, in all of our backgrounds if it were possible to go deep enough, but not as much as Adam and Eve and The Garden of Eden story would naturally imply if one breaks it down.
