Since Africans did not keep written records we will never know. But to give you a clue, the oldest canoe in the world was discovered in Nigeria. A few years ago some African fishermen run into a storm. They landed in brazil three weeks later. "2 out of 5 survived the ordeal. There is an African King that sent out an expedition to discover the world westward many of the huge boats never made it back. Could they be the Olmec? My theory is a bunch of Africans made it to the americas but never returned to their country.<quoted text>Show us negroes that were capable of building a boat able to cross the ocean 3,000 years ago. They couldn't do it 400 years ago.
Show us Indians who look like the Olmec? Why would they make huge stone heads weighing tons that did not look like them.
