Why would Africa be the 'cradle of civilization'?

Is it because of the countries bordering the Mediterranean? Because Africa seems to be barren and devoid of civilization until the last 200 years....

Why does culture get so much more developed in Europe and North West Asia?

Why does cilture develop so much better in Europe if civilization started in Africa?

Looks like they forgot more than they learned.....

Middle east too....I don't believe it was down their either.....too many wars.... Too much crazy.

Any further information to look into this?
