The 5 Hour Video (Existence Unconfirmed)

"The 5 Hour Video" (unofficially named by Anonymous) was first mentioned on /x/, in a deep web thread. Allegedly, an untitled video that is five hours long and contains footge of aliens (and the killing of aliens) was found on the deep web, although many believe the video to be non-existant; a story created for creepypasta's sake.
Despite this, more and more people claim to have seen the video, although it has never shown up online (despite multiple search efforts), and the only "evidence" of it is a supposed screenshot that is unverified. Not much more is known about the mysterious video.
