Here's the problem:

African cultures are the oldest on the planet , thus they have proven means to support their civilizations cultures.

Like for like.

Oldest cultures, but some of the youngest civilizations.

I was being generous.
By them selves, they have not developed any civilization.

Their feudal systems will not allow it. Ideas, influence.... sorry , you cannot be more powerful than a chief who got his chiefdom by successive patrilineage inheritance.I believe that to be the single largest contributor to their backwards state. Hand in hand with the voo-doo, Islam has gotten married to the tribal practices. Thus the people are suppresse and oppressed by their system and Islam. They don’t have to blame whitey. Shit! Look to Zimbabwe as an example of Africans in action!
