Where did they go

Over hundreds of years the Native Americans spread out through North and South America.

Yes, Native Americans are indigenous peoples of the Americas, and their ancestors have lived on the continents for thousands of years. The specific origins of Native Americans are complex and the subject of ongoing research and study. Archaeological evidence suggests that their ancestors migrated from Asia to North America over a land bridge called Beringia, which connected present-day Siberia (Russia) and Alaska (USA) during the last Ice Age. This migration is believed to have occurred around 20,000 to 30,000 years ago. Over time, these early migrants spread throughout the Americas and developed distinct cultures, languages, and civilizations. It's important to note that Native American communities are diverse and each has its own unique history and origins.
