When did the first people start to arrive in America?

The first people are believed to have started arriving in America around 25,000 BC. This timeframe reflects estimates derived from archaeological evidence and studies of human migration patterns. Scientists suggest that these early migrants crossed a land bridge known as Beringia, which connected Asia to North America during the last Ice Age. The presence of ancient tools and other artifacts supports the notion that humans inhabited North America much earlier than many earlier estimates proposed. The possibilities of migration routes and the adaptability of early humans contribute to the understanding of how they spread across the continent over thousands of years.
