Based on the current scientific consensus, it is more likely that the first people who came to the Americas from Asia walked across a land bridge that connected Siberia and Alaska during the last Ice Age. This land bridge, known as Beringia, emerged around 30,000 years ago and persisted until around 11,000 years ago when the rising sea level flooded it.
There is a considerable amount of archaeological evidence supporting this theory. For example, human fossils found in Alaska and the Yukon date back to at least 15,000 years ago, and stone tools discovered across the Americas resemble those used by early human populations in Siberia and Northeast Asia. Additionally, the genetic analysis of modern Native American populations reveals that they share ancestry with East Asians, supporting the idea of a migration across the Bering Strait.
While it is possible that some early human populations may have traveled to the Americas by boat, there is currently no direct evidence supporting this hypothesis. However, recent discoveries of prehistoric human settlements in South America dating back to more than 16,000 years ago, suggest that some early human populations may have used the Pacific coast route to colonize the continent. Nevertheless, these coastal migrations were most likely a secondary process that occurred after the initial Beringian migration.
