This is pretty good proof humans were in Peru 200k years ago. Accepted methodologies used for dating, but mainstream archeology denies it. A lady in the 60s dated some artifacts found to be 200-400kyrs old. Her career is ruined. More recently, her work was validated by 4 other geologists, but that's no good enough. Then the artifacts disappear, they are trying to redig the site for further validation, and their permits are blocked, all kinds of shady things.
