Come on, be fair. What's wrong with admitting the facts presented clearly by this archaeology--that there was once a center of culture, art and learning in Africa? Certainly it no longer exists as such today, but remember that other great civilizations have turned to dust, and so might ours someday.
Of course I was being facetious, but I was having fun at the expense of so-called scholars like Black Studies professor Leonard Jeffries who make all sorts of outlandish historical claims for Africa. For an interesting perspective on this, read "Not Out of Africa: How Afrocentrism Became an Excuse to Teach Myth as History", by Mary Leftkowitz.
It would be great to know what secrets are buried there. If they find ancient documents that chronicle the decline of their civilization, I have a feeling that the stories will be very, very familiar.
