they're flying cow pies...they're bits of scrooge's undigested potato...they're scientifically non existent. when someone gets one good picture, one good video, when a whole plane full of people see it and take selfies with it...then and only then will i come even close to admitting that cryptoanimals live in the sky...the plainly visible, incredibly researched, very well traveled sky...there are no trees for sky big foot to hide behind, no loch rocks for sky nessie to take cover behind, just a few clouds that are transparent to good radar...maybe there are living clouds, because those are the only things larger than birds in the sky that have ever been recorded in anything but a blurry shit video.
i'm not trying to ridicule you, but i do ridicule the whole idea of large animals living in the upper atmosphere, so sorry if a little splashes your way.
there are a lot of animals we haven't discovered yet, but the thing is, most of those animals we haven't discovered yet is because they're nearly identical with species we are aware of, and pass for them, most of the time. most "new" species are just sub sets of pre-existing species that have adapted to a different environment.... .00001 genetic difference....they haven't found anything like a whole new undiscovered species in decades, if not centuries...and i'm pretty sure it's because there aren't any to be discovered anymore.
i've always considered this to be akin to trump derangement syndrome, but in reverse...an irrational unwillingness to accept scientific fact and an embrace of "feelings"...i'll take cold hard facts 10 days out of 9
