The earliest civilizations are believed to have migrated to North America via the Bering Land Bridge, a land connection that existed between Asia and North America during the last Ice Age, around 20,000 to 15,000 years ago. As the glaciers receded, these groups followed herds of large game animals, gradually moving southward and populating various regions of the continent. Over thousands of years, they adapted to diverse environments, leading to the development of distinct cultures and societies across North America.
