in bartolome de las casas' history of the indies it says
"Wednesday 4 days of July he ordered to raise and to give the candles of that island of Santiago in which it says that after it arrived it never saw the sun nor the stars but the skies covered with so thick fog that it seemed that they could cut it with knife and intense heat that anguished them and commanded to govern by the way of the Sudueste that is the road that leads from those islands to the Austro and Mediodia in the name of the Holy and individual Trinidad because then the West of the Sierra Leone and Cape of the West would be Sancta Ana in Guinea, which is below the equinoctial line where it says that beneath that parallel of the world there is more gold and valuables and that they would sail by pleasing Our Lord to the West and from there would pass to this Espanola in which road would see the opinion of the king D Juan susodicha And that he thought to experience what they said the Indians of this Spanish that had come to her from the part of the Austro and the South black people and that brings the Irons from the acagayas of a metal called guanin, from which he had sent the kings the test where it was found that of the thirty-two parts, the eighteen were of gold and the six of silver and the eight of copper.

and it also says
" They came to see certain principals of that island of Santiago and they told him that to the Southwest of the island of Fire, which is one of the same ones of Cape Verde that is 12 leagues away, one could see a island and that King D Juan had great inclination to send to discover the Southwest and that canoes had been found that left the coast of Guinea that sailed to the West with mercadurias "

so did africans travel to the americas or not?
I actually wrote an comment specifically about these claims a few weeks ago.
Spoiler: claims about the "black people" being African are anachronistic readings of the text, which clearly is referring to indigenous Americans.
There's always room for discussion, but perhaps the section Travel and contact across the Atlantic and Pacific before Columbus from our FAQ will answer your inquiry.
