I assume you’ve never seen any, but if you did would you believe? I wondered for years. Saw two, in bright daylight, and now know they exist. And that’s the truth!
Seems a very open question ( a lot of variables) but within reason I'd say yes, I'd believe. But most of what the Believers are shopping is preposterous Freudian boogerbear stuff.
For example, one of their 5 major food groups is of aliens who apparently are traveling the expanse just to poke at our backsides. Why? And this is very important to me nowadays - why aren't those supposedly advanced critters interested in our hearts, literally? We could use a few more podiatrists too, no doubt, and the UK needs even more specialists of all types than we do, but all they seem to get are the hippies who like to romp in the fields, like in a late '60's Hollyweird flick.
Thanks for your first-hand observation. . . . OBSERVATION.
Most Naysayers have NO CAPACITY
to distinguish an observation from a drunken hallucination.
They seem to be severely cognitively challenged.
