Genuine question for the forum: what would it take? Like, not trying to be a wind-up, but everyone says "I want evidence" but then dismisses videos, witnesses, equipment readings, etc.
For me personally, I reckon I'd need a full-bodied apparition in broad daylight in front of fifty people with no other explanation. Or maybe a poltergeist that moves objects on live TV with scientists present. But I know that's probably setting the bar impossibly high.
What's YOUR personal threshold? And be honest - would you actually accept it if it happened, or would you just move the goalposts?
