How did prehistoric people reach the Americas and form settlements?

Prehistoric people are believed to have reached the Americas via a land bridge known as Beringia, which connected Asia to North America during the last Ice Age when sea levels were lower. As they migrated southward, these groups adapted to diverse environments, leading to the formation of various settlements. Over time, they developed agricultural practices, which facilitated the growth of more permanent communities and complex societies. This migration and settlement process occurred over thousands of years, resulting in the rich tapestry of cultures found in the Americas before European contact.
