Answer: The first humans to migrate to and populate the Americas over 13,000 years ago are believed to have been from the Asian continent. This migration is commonly referred to as the "Beringia Theory" or the "Bering Land Bridge Theory."
According to this theory, during the Last Glacial Maximum (around 26,500 to 19,000 years ago), much of Earth's water was locked up in glaciers, causing sea levels to drop and exposing a land bridge known as Beringia that connected what is now Siberia (Asia) with Alaska (North America). It is believed that early humans, often referred to as Paleo-Indians or Clovis people, migrated across this land bridge from Asia into North America. From there, they gradually spread and populated the Americas.
These early human populations are thought to have been the ancestors of the indigenous peoples of the Americas, including Native Americans, Inuit (Eskimo), and various indigenous groups across North, Central, and South America. The migration and peopling of the Americas is a complex and fascinating part of human history, supported by archaeological and genetic evidence.
