America Before

According to scientific consensus, it was widely believed until recently that humans migrated from Siberia to the Americas approximately 13,000 years ago, crossing the Bering landbridge into Alaska. Over the next two millennia, their descendants supposedly dispersed through Central and South America, ultimately reaching southern Chile by around 11,000 years ago. Meanwhile, as the Ice Age came to an end and sea levels rose, the Bering landbridge was submerged, effectively isolating the Americas from the rest of the world.
