There was a land bridge due to lower sea levels during the last glaciation. HOW people from Asia populated the Americas is not really the question.

But now they are saying that people were here before the land bridge was usable or existed, right? So, maybe they came some way other than the land bridge. Or, earlier peoples came via some other route (hence the current footprints) and then a later migration came via the land bridge.

Actually, that absolutely is the question.
