For example, how many people are aware that the Bering Straight Land Bridge theory has been debunked?
Why would they call it a land bridge when it should have has a glacier covering it that was several miles deep and that ice should have covered part of the Pacific ocean that would have been to the south of that piece of land. Same with the Atlantic, Greenland and Iceland could have been completely under the ice. They would not have even needed boats, they could have walked on the ice close to the shore, fish for food and ice for fresh water could have met most of their needs. Warm clothing would also be needed but other than that nothing would be a necessity for life.
