I'm acknowledging it now
. The thing about this challenge is it doesn't accommodate for the seemingly inexplicable events that occur on a ad hoc basis. It's not fit for purpose for dealing with "genuine" phenomena that occurs spontaneously.
It's ideal for the all too common claims of reliable and repeatable paranormal powers, though. Foretellling the future, magic healing, seeing into the past, communicating with the dead/spirits/aliens/whatever, etc.
As for "seemingly inexplicable events that occur on a ad hoc basis", the most likely reason for those is that nobody present has an explanation, not that there isn't an explanation. The idea of "I can't explain it, therefore it's magic/gods/spirits/aliens" has a widespread and enduring appeal, but it's just a way of avoiding saying "I don't know" because most people very much dislike saying "I don't know".
A few days ago a coat hook I had stuck on a door a while ago fell off. Why did it fall off at exactly that time? It didn't have anything hung on it at that time, so it wasn't due to an excessive load. That is a "seemingly inexplicable events that occur[ed] on a ad hoc basis", so does that mean it's inexplicable? Does it mean that a magic-user/god/spirit/alien pulled the coat hook off? No. It just means that I don't know why it happened at that time.
Not so long ago, most (if not all) people thought that lightning was paranormal and usually a weapon of a god. Does that mean that lightning really was thrown by various gods in various parts of the world back then and only became a natural phenomenom recently? Why did all the gods of lighting retire at the same time? I have this odd image of Odin and Indra and a whole bunch of other gods getting together for a party to celebrate becoming eligible for a pension and finally being able to retire
EDIT: Oops, wrong god. Thor was the thunder god, not Odin. Although maybe they believed Odin could do it too, I don't know.
