Who Really Discovered the Americas?

If you thought that Christopher Columbus discovered America, you are way off base, in fact the Norse didn't discover it either. To investigate how the Americas were settled, one must travel back in time to the very first settlers that walked with the dinosaurs. The Americas were rediscovered over and over by the Sumerians, Egyptians, Phoenicians, Geeks, Romans and even by some from Italy and Portugal before Columbus came along.
