Opinion: Another species of hominin may still be alive
https://en.wikipedia.org/wiki/Homo_floresiensis claims that the most recent fossils are about 50,000 years old.  Without more recent bones, we have no reason to believe that they still exist.That said, myths about both small human-like animals and large ones are practically universal.  We have another universal myth that was fairly recently dated to be much older than you'd expect.  https://theconversation.com/the-worlds-oldest-story-astronom... shows that the myth about the Pleiades, aka "seven sisters", likely date back 100,000 years.  Given that, would it be surprising that myths like the Sasquatch date back to folk memories of Neandertals?  Who our ancestors knew much more recently than that?
