I think we need a few hard-liners out there like yourself
"Hard-liners"?!? When did sober rationality suddenly become a radical, hard-line stance?
I conceed that it could be true that no UFOs reported so far were alien craft.
Congratulations, J.R., you're making progress!
Am I correct in believing that this concession extends to your own sighting experiences as well?
However let me ask you this: Although you default to your null hypothesis
He defaults to it because
that's what it's there for: to be defaulted to, until some evidence can be produced that reliably proves it wrong.
...do you also acknowledge that some UFO reports could have been alien craft and there simply isn't enough evidence...?
I do.
It's also hypothetically possible that UFOs are the result of gods, angels, ghosts, time traveling Nazis, creatures surfacing from deep within the Hollow Earth, sky-fishes, the Flying Spaghetti Monster, the Pleasure Ships of the Sex Goddesses, cryptozoological gooseblimps, and any other unfounded, unprovable explanations.
Depite all that, if some real evidence were to arise that conclusively indicates that intelligent ET exists and has been visiting our planet I'd most certainly be willing to admit that some UFO reports
could have been alien craft.
...to prove it to your satisfaction?
(emphasis mine)
See, this is where your reasoning broke down.
This is not a matter of RoboTimbo's
satisfaction. When I'm looking at a claim regarding the physical world, I don't think to myself, "Gee, I better ask RoboTimbo's opinion about this" (Sorry, Robo).
These matters are not determined by any one person's opinion. This is not a cult of personality wherein some leader charismatically states an opinion and we're all are bound in faith to accept it as dogma. Personal opinions carry no weight where objective reality is concerned. Knowledge of the material world is determined through the evaluation of measurable, verifiable and repeatable evidence.
Uninformed personal opinions have no bearing on reality. Anecdotes are mere claims, not evidence. If you go around making conclusive claims about the nature of the Universe on the basis of hearsay and personal authority, that's called
pseudoscience.
