Two 'time travellers' who claim to come from 2027 have been sharing videos which they say prove they are alone in the future.
Javier and Maria have been posting on social media claiming to be stuck alone in 2027 with only each other for company and "no sign of human life".
Neither of the self-proclaimed time travellers ever show their face in the apparent clips from four years' time which are clearly deserted.
Maria, who claims to be a scientist and goes by the TikTok username of @socmia, says in her bio: "Time is an illusion. Alone in the world with unicosobreviviente."
In one clip, Maria said: "Hello, I am Maria. I am part of the same project as Javier (who you know as unicosobreviviente).
"I appear here because I am still processing everything I have lived and I am trying to find a solution.
"I still have a lot to understand but I have decided to change the current situation.”
Among the videos that she has posted for her 129,000 followers to view, Maria filmed the couple walking down the stairs on an apartment block without any interaction with anyone.
She also reposted several of Javier's videos, including being alone on a runway alongside with a stationary plane.
One person queried: "If you're alone then who is running TikTok?", while another asked: "These videos don't prove anything... where is the supermarket, the streets and a newspaper date???"
A third commented: "No people left in the world. But you're wearing pretty new and cheap Puma shoes where you could have any shoes, boots from any shop."
A fourth person wrote: "Break something? If no one is there then there's zero consequences."
Javier's TikTok account @unicosobreviviente has more than 7.6 million followers and the videos on his profile see him venture into a completely empty McDonalds restaurant with footage shot outside of Atletico Madrid's football stadium without a soul and also quick clips of deserted streets.
He also claims to have filmed a completely deserted street at 8.10pm where the only cars on the road are the ones parked and there is not a hint of background noise in what should be a bustling street.
