12 and a half million slaves hummm! Even the TITANIC BUILT IN 1909 COULDN'T CARRY 12 and a half million slaves out of Africa at this time. I'm just saying the science is not adding up to me. Even til this day how many years would it take to move 12 million people on Ships. Still can take up to 6 months to take one trip ..a year round trip! the Atlantic Ocean hasn't shrunken.
