Valencia (Spain) - Imagine waking up in the future and being the only person in the world. Sounds crazy, but this is the claim of a man from Spain who walks through deserted cities on the Internet in front of an audience of millions, stays in forbidden places and keeps his viewers in suspense with the threatening atmosphere of the end of time. But what is the truth about the supposed time traveler?

It all started with a post on July 21, 2021 on "X" (formerly Twitter). The man, who calls himself Javier, wrote: "I just woke up in a hospital and I don't know what could have happened. Today is February 13, 2027 and I'm alone in the city. I am the only survivor."

Since then, Javier aka "Único Sobreviviente" ("The only survivor") has been traveling around trying to convince his followers that there will be no other people besides him in 2027.

Whether in places that are usually crowded with tourists at any time of day, forbidden places like the Vatican , on a cruise ship or in shopping centers: the Spaniard has been everywhere and always seems to be alone.

As if the lonely situation wasn't depressing enough, the supposed time traveler always accompanies his videos with the appropriate music.

On TikTok , for example, more than 9.7 million users now follow the Spaniard, who apparently lives in a parallel universe that is connected to the present in some way, which is why Javier is able to provide his followers with regular posts. He has also dared to make a few prophecies, such as the hurricane in South Carolina in September 2021.

But are TikTok and co. actually witnessing a time traveler here?

Even though the videos of the "sole survivor" are really well made and have great entertainment value, critical voices are raised under each post by users who don't believe Javier's story one bit.

After all, watching the videos raises logical questions, such as how he manages to move so effortlessly and quickly between the many European countries. Some users are also keen to spot image errors that reveal that the footage was edited before it was uploaded.

It is also noticeable that the electricity and internet still work in every location, there are fresh footprints on the beach and the public advertising is up to date. The vegetation in the cities also appears to be well maintained, and the grass in the soccer stadiums has not grown out of control.

It is also more or less obvious that the videos of Javier are merely staged and that the other people have been cut out with the help of an AI. Nevertheless, the insight into a deserted world is always exciting!
