Best Answer

For ancient American civilization, scientists speculate that people walked across the Bering Strait during the ice age. This would explain HOW Native Americans were on the North and South American continents long before the discovery of the New World. They base this theory on the fact that in the ice age the Bering Strait was above sea level.

An opposing theory might be that Native Americans were on the continent before Pangaea completely broke apart.

Theory: One historical theory is that ancient American civilizations originated from migrants who crossed the Bering Strait during the ice age. Fact: During the ice age, the Bering Strait was indeed above sea level due to lower global sea levels, which could have facilitated human migration between Asia and the Americas.
