Yes, all those superior abilities are impressive. If it weren’t for white people there wouldn’t be a single two-story building anywhere in Africa today.
Actually Timbuktu (sp?) had quite interesting buildings made of mud or stucco type material that were more than one story. Sadly the builders were moslems. Interesting looking buildings, look as though they wouldn’t survive a couple of heavy rainfalls.
