Penultimate Amazing
IF...IF...IF there is something, we must not be looking in the right place.
We're looking exactly where the claimants tell us to look. If we're not looking in the right place, neither are the claimants.
The upshot of this is, whatever is being claimed isn't being found. Ghosts, bigfoot, clairvoyance, telepathy, etc. None of these exist as claimed. We've pretty much ruled out the entire category of claimed paranormal phenomena.
Your complaint is that nobody has bothered to try to invent a test of something nobody has ever even claimed.
Meanwhile, science continues to find new things all the time. Not by arbitrarily inventing tests of things nobody has even thought of yet, though.
