The most widely accepted theory on how early humans migrated to North America is that they walked across the Bering Strait, which was a land bridge connecting present-day Russia and Alaska during the last Ice Age. This land bridge, known as Beringia, emerged when sea levels dropped due to large amounts of water being locked up in glaciers. This allowed early humans to travel from Asia into North America by walking across the Beringia land bridge.
