Answer:
It was far away and the last continent to be settled.
Step-by-step explanation:
The Americas were located across the Atlantic Ocean from Africa, the place of origin of the human species. When humans began migrated out of Africa, they did so following the easiest land routes. As such, humans arrived to China and Europe much sooner than they arrived in America.
It has been speculated that humans first arrived in the Americas from Asia. This is presumed to have occurred by crossing the Bering Land Bridge or, possibly, the Pacific in boats from Polynesia.
Even during the European Age of Exploration, sailing across the oceans was a massive feat, and no one really new what awaited hapless mariners on the other side. When they arrived, they found lands that were settled, but they were not the islands they had been looking for.
