Listening to Graham Hancock, I have only recently learned that the "Clovis first" theory that people arrived to the Americas only 13k years ago, belongs to the 1970s. Since then, there have been findings of much older human presence:
Bluefish Caves, Yukon, 24k years ago
Old Crow Flats, Yukon, 25k-40k years ago
White Sands, New Mexico, 21k-23k years ago
Hartley Mammoth site, New Mexico, 38k years ago
Cerutti Mastodon site, San Diego county, California, 130k years ago
Monte Verde, Chile, 14k-33k years ago
