Who were the first people in North America? From where did they come? How did they arrive? The thought about when people first reached America in about 12.000 years ago was a long time thought of as an absolute truth by the establishment in science. This version was so accepted that few archaeologists even bothered to look for artefacts from periods before 10,000BC. But when people did, they found that people have been living in America for at least 16.000-20.000 years. But that is problematic because science has a long time thought that the "gate over Bering Strait" from Asia was closed in that time by the ice masses of the ice age.
