Given<p>1. a site that appears to have been used by humans to do some kind of processing of bones, and<p>2. very old (130k) bones at that site that have been processed,<p>how would you rule out the possibility that the site was made and the bones processed by people that came much later (say, 15k years ago) who <i>found</i> a bunch of 115k year old bones from animals that died from natural deaths and used them?
