And your claim is that the DNA of Africans is different than that of all other people in the world? And better than that "other" DNA? You seem a bit "pressed" in that matter. Apply that sage wisdom to yourself, perhaps?
Granted, towns were built deeper into the African continent than Egypt with buildings, art and architecture that rivalled that of ancient Greece and those places haven't received the attention from the 'white' world they deserve but that is not a reason to assume that 'black' DNA is superior, or even 'different' than the DNA found in al humans as you seem to be claiming.
