you and the OP dont even know what you are arguing against. Van Sertima is NOT the first to make the claim of an African presence in Precolumbian America. He had much skepticism when the theory was presented to him until he studied and researched, then came to his own conclusion. The bullshyt you and the OP kicking about "Afrocentricts" pushing pseudo-science says more about yall than actual objections to the theory.
For the record, this white German born Mr. Burns looking dude is the one who came up with the "Afrocentric pseudo-scientific" theory of africans in pre Columbian America. Let that sink in.
To those who enjoy subjects like these, in addition to "They Came Before Columbus" check out Von Wuthenau's book.
its expensive, i was able to borrow it from my professor in college. Ill add it to my book collection one day.
