The exact timing of when Paleo-Indians, the first humans who inhabited North America, arrived is still a subject of ongoing research and debate among archaeologists and anthropologists. However, most scholarly estimates suggest that the first Paleo-Indians arrived in North America around 15,000 to 20,000 years ago.
Paleo people, also known as Paleo-Indians, arrived in North America around 15,000 to 20,000 years ago. The exact timeline is still debated among scholars, but evidence suggests that the first inhabitants crossed over from what is now Siberia, using a land bridge called Beringia that connected Asia and North America during the last Ice Age. As the climate warmed and glaciers receded, these early migrants gradually spread throughout the continent.
