99 percent uploads are either faked or simply reflections, mostly through glass, windshields etc..

I recall one that glpers were getting excited over, soon as i looked at the video i fuckin pissed myself laughing, the ufo was a fuckin ceiling lampshade reflecting through the front window at a local bar.no joke.

Another one was a stream of objects passing below cloud cover, when i zoomed in turns out it actually was a flock of geese yep fuckin birds wings flapping in unison and all.

As for big foot sightings, why is it always some Louisiana swamp man fella with one eye no teeth and married to his sister that claims his first encounter with ole big foot,an inquiry soon discovers he had a big night on moonshine with ole Doris johnson or peg leg annie they called her, yep she has about as much facial hair as big foot himself.

Or some twit uploads my personal fav for laughs a crop circle all bendy and spiraling out consistent with ole Bill Daily the local pastor who snuck out one evening with the local choir girl for some shenanigans. Anyway with rope flat board they soon had themselves a fine lookin crop circle which the very next day the local rag printed up as alien in nature.

Now you can quite easily create a ufo stick it up ole uncle jeds chimney and make it look like the real thing for click bait enthusiasts to pontificate over.
