Most scientists and archaeologists agree that nomadic hunters and seafarers migrated to the Americas from Asia, specifically crossing the Bering land bridge around 15,000 years ago. This theory is supported by genetic, archaeological, and linguistic evidence.
Archaeologists have confirmed that Africa, specifically the East African region, is the birthplace of humankind. Fossil discoveries, such as those in Olduvai Gorge in Tanzania and the Rift Valley in Kenya, provide evidence of early human ancestors living in this region millions of years ago. These findings support the "Out of Africa" theory, which suggests that modern humans originated in Africa and migrated to populate the rest of the world.
During the Ice Age, people migrated in search of food and shelter. Initially, early humans followed animal herds across land bridges like the Bering Land Bridge. As the ice sheets retreated, populations moved into new territories, adapting to different environments and developing new technologies to survive. Eventually, populations spread across the globe, moving into Europe, Asia, and the Americas.
Scientists use a variety of evidence to study early migration, including genetic analysis of modern and ancient populations, archaeological artifacts, isotopic analyses of human remains to trace diet and geographic origin, and studies of ancient pollen and plant remains to reconstruct past environments. By combining these different lines of evidence, scientists can piece together the story of how humans migrated and settled around the world.
During the Neolithic Era, people migrated to various regions around the world including the Middle East, Europe, Asia, Africa, and the Americas. These movements were often driven by factors such as changes in climate, population growth, and the search for new resources for agriculture and settlement.
It is believed that Neanderthals did not reach America, as they primarily inhabited Europe and parts of Asia. Modern humans, who coexisted with Neanderthals in Europe and Asia, eventually migrated to the Americas via a land bridge known as Beringia that connected Siberia to Alaska during the last Ice Age.
The first people in the Americas were bands of hunter-gatherers.

Native Americans never migrated to the Americas. It was the Europeans that migrated here and the only thing they found was Native Americans. Native Americans have been here since the beginning. Hence the name Native AMERICANS.
People migrated from Asia to America by crossing the Berring Straits. At that time, the land was connected and one didn't have to cross an ocean in order to get to the Americas.

They believe a land bridge existed between what is now Russia and Alaska. Sea levels would have been lower at the time due to the amount of ice on land.
They migrated through the Bering Straight and down through Canada.
