Scientists believe the first people migrated to the Americas around 15,000-20,000 years ago based on archaeological evidence, such as ancient artifacts and DNA analysis. The prevailing theory is that these early migrants crossed a land bridge that connected Asia to North America during the last Ice Age.

The early people migrated South for food clothing and better jobs.
The land bridge theory suggests that around 10,000 years ago, a land bridge called Beringia connected Asia and North America, facilitating the migration of early humans into the Americas. This theory helps explain how humans first populated the Americas by crossing from Asia into North America.
Bering Land Bridge Theory: This theory suggests that people migrated from Asia to North America by crossing a land bridge that connected Siberia and Alaska during the last Ice Age. Coastal Migration Theory: According to this theory, early humans traveled along the Pacific coast by boat, following the shoreline to reach the Americas. Solutrean Hypothesis: This hypothesis proposes that people from Europe crossed the Atlantic Ocean via boats along the northern ice edge to reach North America. However, this theory is controversial and not widely accepted by the scientific community.
This matters if you mean when the early humans found it or when Europeans found it. Yes, when the Europeans found America, there were native Americans, but no one knows if there were people when the Native Americans migrated there.
