No one nos for sure how the Native Americans came to North America, but there are three possible ways. Those are Land Bridge, Ice Bridge, and Continental Shelf. The Land Bridge is when the water sunk and you could walk on the land that was left. The Ice Bridge was when all the water frooze after the ice age, and it was hard enough for them to walk across. Last one was the Continental Shelf its when the lands were together by a small path with water on both of the sides. The one that I think was the one they used was the Continental Shelf, because there has to be a time when though two lands were together. So they could have talked over it before the two lands split.
