How long have humans inhabited the Americas?

Humans are believed to have inhabited the Americas for at least 15,000 years, with some evidence suggesting they may have arrived even earlier, possibly up to 30,000 years ago. The initial migration is thought to have occurred via the Bering Land Bridge, which connected Asia and North America during the last Ice Age. Over millennia, these populations spread across the continents, leading to the development of diverse cultures and societies.
