re: How do you explain the origin of the various human races scientifically?

I'm not defending 8Up's statement, but what would you expect to find from an ancient garden - a garden that had nothing but vegetation? How would you expect to positively identify the recovered remains of a person several thousand years old? Also, the political climate of the region has made archaeological expeditions almost impossible.

Again, I am not arguing the points of 8Up, I am merely stating the flaws in your statements.
