There was really no reason people came to Americas because Christorpher Columbus thought that America was Asia. He though that because he didn't know that there was land that blocked Asia. His goal was to reach Asia because there were stories that said that there was gold in Asia so Christopher Columbus wanted that gold.
The Bering Land Bridge was is believed to be one of the first routes that Asian people used to migrate to america.
The Bering Land Bridge is the land where people crossed from Asia to America during the last Ice Age. This narrow stretch of land connected modern-day Alaska and eastern Siberia, allowing early humans to migrate from Asia into North America.
No they could not
North America and Asia were connected by a land bridge known as Beringia during the last Ice Age. This land bridge allowed early humans to migrate between the two continents.
The Beringia land mass was visible to early peoples due to lower sea levels during the last Ice Age, which exposed the land bridge connecting Asia and North America. This land bridge allowed early humans and animals to migrate between the two continents. As glaciers melted and sea levels rose, Beringia was submerged, but it played a crucial role in the movement and settlement of prehistoric populations.

Birds that migrate generally do so on a North-South axis. Many birds that live on the Asian continent migrate throughout Asia. It would be unlikely, or "accidental," for birds from, for example, North America, to migrate to Asia.
