Not incorrect measurements of the earth’s circumference, rather he used incorrect maps that showed Asia as being like 4 times bigger than it actually is, with the Polynesian islands and Japan being a continent sized chain, each at minimum the size of Sardinia

And the reason why Columbus managed to get funding for his journey was because he used incorrect estimations of the earth’s circumference, which indicated a much shorter distance to India than previous (much more accurate) estimations.

Oddly enough it seems the same is true for Mansa's trip. Except that as regent, he gave himself the funding, twice.
However, as wikipedia notes: ( https://en.m.wikipedia.org/wiki/Atlantic_voyage_of_the_predecessor_of_Mansa_Musa )
In addition. The dark skin of some South Americans is genetically distant to modern Africans, but has ties to the same markers in some asian cultures, implying its addition was prehistoric and happened in the old world.
