Fundamentalists...still another question regarding Adam and Eve......?

A step further, how did the world get repopulated from Noah's time? Noah's wife was black, so his sons had to be half black... so we are all black to one degree or another? this isn't that far fetched, in that science is still basically Afro-centrist as well. but accounting for 6 billion dilutions from an 8 person gene pool or a 2 person gene pool is statistically insignificant.. simply impossible..
