Random thought that's been bugging me: We assume anything we can't verify must be supernatural or misidentified. But we're constantly discovering 'extinct' species that are actually still living - the coelacanth, the tree kangaroo, new primate species in Southeast Asia...
What if cryptids aren't cryptids? What if we're looking at survival populations of thought-extinct animals? A Thylacine in Tasmania. A giant ape in the Congo. These aren't paranormal - they're just zoologically unexpected.
The problem is that cryptozoology and paranormal investigation got bundled together, and now anything cryptid-related is treated as pseudoscience. But legitimate zoologists discover new species every month. Why is it mad to suggest the Tasmanian Tiger survived? Or that populations of large unrecorded primates exist in remote regions?
