There's some genuinely weird shit unexplained, I'll give you that. Unlike Bigfoot, where you can look at a map of the historical range of bears and see it exactly matches where all the Bigfoot sightings are.

The US South has bears.
The trend is pretty clear.
Just to go off of this.. I'm not saying it was aliens.... but it was aliens.
