Surprised to find no mention of an asteroid/comet impact[1] ~12kya that would have destroyed almost all evidence of prior human habitation. [1] https://phys.or

  >Surprised to find no mention of a theoretical asteroid/comet impact... Fixed that for ya (based on the title of your link). Given that the article in question here suggests people were in Oregon ~18,000 years ago, that's about a ~5200 year gap for what was found here to have been buried enough to, one would imagine, withstand what occurred in your link.

    Also, the impact was thousands of miles away, and we're talking about stone tools. They would have mostly been fine on the surface, too.

  That article says nothing about an impact destroying evidence of habitation. That seems impossible to me; dust and fire couldn't destroy stone tools, especially ones that are under surface dirt already.
