No signs of humans have been found in the Americas from before the last glaciation. The first known objects found are stone tools dated at 15,000 years old, during the last part of the glaciation. From various archaeological sites from Siberia to Alaska and down the west coast, evidence has been found linking native American DNA with that of Asian origins.
