Explanation:

In 1507 the cartographer Martin Waldseemüller published the first world map in which the newly discovered continent was given the name of america, on this map it is observed that it is completely separated from Asia, which until then was not considered, since it I thought that the new lands discovered were part of the Indians in Asia. It can be seen that the vast majority of what was known of America until then was the southern part.
