I'll agree to that. Anecdotal evidence is evidence. But we need to keep in mind how incredibly bad it is as evidence. It's like taking publication bias and making it an art form. I believe alt med lives on anecdotes (note: at least SOME alt med must be incorrect, since some alt med contradicts other alt med, eg magnets are good vs EMF is bad).To say there is NO evidence is a lie. Also, anecdotal evidence is evidence. It doesn't qualify as scientific evidence, but that specification is almost never included. It is a common mistake made by those who misrepresent the facts; be it intentional or not.
What frustrates me is people arguing over what 'really' happened when all they are going on is a few short sentences about the event. It doesn't matter if their theory is paranormal or scientific; they don't know what they're talking about.
I do like that, as we observe more and more of the world, we can actually show some these things exist. You mentioned a bunch of them ("...ball lightning, earthlights, earthquake lights, sprites/jets/ELVES/TIGERS..."). Keep it up, NASA and others.
