I don't for one moment believe that all human beings are descended from a common ancestor(s) in Africa. That's another scientific theory which I figure is just part of the picture, but not all.

To just believe these officially stated things is as facile as just believing what some church tells you...in either case, it's merely an opinion passed on by an authority structure which is far from omniscient, and which has already been proven wrong in its cherished assumptions time and again throughout history.

Just wait and see...

There will be new theories and new evidence soon enough.
