Cool! I think I remember hearing about them a while ago. I did create a Facebook account in 2006, and I've used it a total of one time since then. 😅 But if any good folk around here know about it, they can forward this post so they can have a good laugh. I'm fairly sure this rock is from here, even human as you said, so maybe it's better that the mystery remains and not be quashed in the hard logic of truth.
It might be something like that too. Didn't know how to test for it though. It might be another rabbit hole.
There are groups on facebook where people post their rock finds to be identified
