Historians and Anthropologists agree that Ancient Indians migrated from Siberia to North America approximately 14,000 years ago. They were hunter-gatherers from the Paleolithic that came from Asia to North America when they crossed the Berin Strait that was frozen due to the extreme cold temperatures of the time. They crossed from modern-day Russian territory to Alaska, and they descended through North America, following herds to hunt them and feed their families until they started to settle in some places.
