I would have to experience that first hand - be abducted myself.
But how you would you know that what you experienced was real?
Clearly not all that people experience is actually real....
Do you believe that those claiming to have been abducted and experimented on, really were?
I'm guessing you don't. Yet, these people are
extremely convinced. They pass lie detector tests and everything.
Consider a schizofrenic in accute psychosis. This person
literally sees and hears things that aren't there. They also experience sensations etc. If their hallucination tells them that a a spider is crawling up their leg, they
literally do feel a spider crawling on their leg. You can put them in a brainscanner and you will see the neurons firing up. But there is no spider there.....
So while "experience" clearly can make you
believe things... they can not be considered evidence/proof that those things are actually real.
So I'll rephrase then..... barring "personal experience of abduction", what kind of evidence would convince you that what these people claim, is actually true?
How about........ if they snatch something of a shelve inside the space ship while being abducted? As Neil deGrass Tyson once said "
if you manage to steal something -anything- from an alien space ship, of alien manufacturing, that likely originated lightyears from earth... it is bound to be interesting!"
Wouldn't that be a nice first step?
Are you willing to experience having a demon or 2 manifest and be kicked out of your own body?
If you can make that happen on command in a repeatable way, go for it!
