The disguised man, who introduced himself as Lewis Walker from Leicester, claimed to have been to the future as part of a secret Government time travel program.
The alleged time traveller said in the distant year of 4413 flying cars will take over the skies and machines will replace human flesh and bones.
Mr Walker said the only people not assimilated by robots in the future will be other time travellers like himself, who often travel to that particular point in time.
In 4413, only human-robot merged hybrids will supposedly “remain”.
Speaking to paranormal investigators from YouTube channel ApexTV, Mr Walker said he has seen unimaginable wonders on his journey.
The time traveller said: “I thought it was amazing they allowed time travellers to visit.
“I spoke with a few of the robots and they were the nicest people I had ever talked to.
“Even though they were way more intelligent than any human they had warmth and kindness to them that was unmatched.”
Until now, the only people who have ever heard Mr Walker’s story were his wife, his children and the people who orchestrated his venture into the future.
According to Mr Walker, he was induced to the Ministry of Defence by his father and by 1977 worked his way up the ranks until he was given clearance to time travel technology.
The time travel program was supposedly looking for test subjects to send forward in time from a “top secret base at the bottom of the English Chanel”.
He said: “They’re not going to like that I’m saying this but so be it.”
However, not everyone was convicted Mr Walker’s bizarre time travel story was a genuine account of the far future.
The Apex TV video, which has been seen by more than 10,500 people, was criticised for being staged and “fake”.
One person, Claire Reid, commented: “It would be more believable if he didn’t sound like he was reading lines.”
Robert Quill said: “Sounds like he’s reading from a script.
“There’s no way he could be that fluid in his storytelling unless he was an actor.”
Scientists have long debated the possibility of moving back and forth in time with ease but the general concuss is that this is a highly unlikely scenario.
William Hiscock, a professor of physics at Montana State University, said: “Time travel into the past, which is what people usually mean by time travel, is a much more uncertain proposition.
“There are many solutions to Einstein’s equation of General Relativity that allow a person to follow a timeline that would result in her or him encountering himself – or her grandmother – at an earlier time.
“The problem is deciding whether these solutions represent situations that could occur in the real universe, or whether they are mathematical oddities incompatible with known physics.”
