Sergeant Clifford Stone claimed that in 1973, he was involved in the retrieval of a crashed extraterrestrial craft.
He claims that he hid a small piece of the craft’s metal exterior in his boot and buried it near his home in New Mexico, Nevada, US, after leaving the US Air Force in 1989.
The man also bizarrely claims that prior to his departure, he had catalogued 57 different species of aliens.
Some, he states, looked very much like human beings that could walk among us and wouldn’t be noticed.
YouTube conspiracist Blake Cousins – of thirdphaseofmoon – has since uploaded a video of a conversation he had with the former US army soldier.
In the clip, the former soldier: “Yes I have it and wouldn’t dare to keep it in the house.
“I had it here to show some people where I kept it, a day longer than I should have and then somebody actually came here and tried to take it.
“That was some tense moments, I almost shot somebody that day.”
Blake now believes his conversation with the former sergeant “could change history as we know it”.
Sergeant Stone later added that the piece of debris that he claims is part of the UFO is irreplaceable.
He added: “I can’t replace this, you don’t go to the store and buy this and I took a big chance when I went ahead and got it.”
Another wild conspiracist known as Dr J later detailed that after the Roswell UFO incident in 1947, an individual who claimed to have had a piece of the ship’s metal had to hand it over to the USAF.
Dr J bizarrely added: “I would think after reconstructing the craft themselves, they too wanted it back.”
“So the very existence of this extraterrestrial object from a spacecraft which he has buried is dangerous for his safety and for all of ours.”
It comes after a tourist filmed “UFOs” emerging from a giant red cloud.
