I doubt many folks insist it's all fake, most I think, know that there are real accounts of unidentified objects in the sky. It's the aliens, interdimensional travelers, ancient aliens, abductions and that ilk most folks find unbelievable.
Edit. Who is the Denialist? Quotes from Neil Degrasse Tyson.
"The evidence is so paltry for aliens to visit Earth, I have no further interest."
"The universe brims with mysteries. Just because you don't know what it is you're looking at doesn't mean it's intelligent aliens visiting from another planet,"
Neil Degrasse Tyson.
Is Mr. Tyson a bit of a denialist himself?
