The belief that the earliest Americans migrated from Asia is based primarily on DNA research. DNA evidence proves people from the Bering Strait down to Tierra del Fuego are descended from native Siberians.

Where was there more room where Native Americans came from or the new world?

As native Americans believe they have always been where they are (ignoring the forced movement to reservations) the amount of room is identical! Archaeology and genetics show they migrated from northern Asia during the last ice age. The migration was probably simply caused by following their food as the animals migrated. It is unlikely that they encountered any significant changes in amount of room as each group migrated.
