i belive theres @ least 15,000 migrations on the brig but you may have to do more research
They crossed over the land bridge called Beringia
they came across a ice-land bridge from Asia
They thought the America's would have better food and farming.

The Beringia Land Bridge
Central America land bridge
The Bering Strait
the last people to cross the bridge were the natives to the Russian/Alaskan areas..
The Bering Strait has been a significant migration route, particularly during the last Ice Age when lower sea levels exposed the Bering Land Bridge. It is estimated that multiple migrations occurred across this land bridge, with the most notable being the initial migration of humans from Siberia to North America around 15,000 to 20,000 years ago. While exact numbers of migrations are difficult to determine, genetic evidence suggests that these early populations diversified into various groups over time. Subsequent migrations may have occurred as conditions changed, but the primary wave is often considered the most critical in human prehistory.
The land bridge was covered with snow that melted and it is now known as the Bering Strait.
Neanderthals did not migrate across the Bering land bridge as they primarily inhabited Europe and parts of western Asia. The land bridge was used by early human populations to migrate from Asia to the Americas.
The second one.
The Beringia land bridge and ice bridge are not the same. The Beringia land bridge refers to a former land connection that existed between Siberia and Alaska during the last Ice Age, allowing animals and humans to migrate between Asia and North America. The Beringia ice bridge, on the other hand, is a theory that suggests that during certain periods of glaciation, sea ice in the Bering Strait may have connected the two continents, facilitating migrations.
The earliest inhabitants of the Americas were thought to have come across a land bridge from Asia, based on anthropology as well as genetic evidence.
The American Indian come to North America from Siberia across the Bering land bridge.
