I need to find this again but when the white man showed up in Africa they asked the niggers where their roads and building were. The niggers had been there for millennias and never domesticated any animals, built a road, the only shelter were mud huts and that itself wasn't practiced everywhere. The only exception were the muslims and then came out of Arabia and colonized north Africa. The smarter chugs in America had come up with shelters they could set up and take down and Mayans were just this side of an agricultural civilization. I still don't believe they built the pyramids there. Someone else did that.
