How did the first Americans get to this continent? How do we know about these people? Short answer 3-4 sentences.

Answer 1

The first Americans are believed to have arrived in the continent via a land bridge called Beringia that connected Siberia (Russia) and Alaska during the last Ice Age. This enabled human migration from Asia to North America around 15,000 years ago. Our knowledge about these early American people primarily comes from archaeological evidence, such as ancient tools, fossils, and human remains, as well as genetic studies and oral histories passed down by indigenous communities.
