The origin of these inhabitants has been the subject of much scientific research and discussion. Most archaeologists agree that the first Americans, the true "discoverers" of America, came from northeastern Asia. There is also a great amount of proof that these inhabitants crossed over the 55-mile-wide Bering Strait that separated Asia and North America when a land bridge existed. They had been in the Americas for nearly 15,000 years. To get to the Americas, these people should have crossed between Asia and North America. According to one theory, these people crossed over during the last Ice Age when the Earth's water froze, and the sea levels dropped, making it possible to walk from Asia to North America.
