There’s a term for this idea, “preternatural”. It means a phenomenon that is the result of the natural world, not magic or divine, but still unexplainable with our current understanding.
James Randi’s prize didn’t require proof of the supernatural, it was open to preternatural phenomena as well. Someone just had to prove it was a REAL phenomenon and not a hoax or random chance.
Birds fucking love yelling. If you want to be a parrot’s best friend, start yelling at them. They think that shit’s hilarious.
