The first Americans crossed into North America from Siberia over 30,000 years ago via a land bridge that connected Asia and North America during an ice age. As the climate warmed, sea levels rose and the land bridge disappeared, leaving early Americans isolated in their new environments across North and South America. Native Americans developed diverse cultures as they adapted to the varied natural resources and climates of different regions, though they shared some common beliefs like respect for nature and limited ownership of land.
