Popular UFO hunter Scott C Waring believes he found evidence of alien fossils and spacecraft in NASA’s official photos of Mars.
The conspiracy theorist shared stills of the Red Planet, snapped by one of NASA’ robotic rovers, claiming they were proof of aliens.
Pointing towards a photo of a rock, Mr Waring said: “This object does appear to be technology. Can you see the long tunnels coming out of this? The long tube?
“There’s kind of two round, tubular, larger pieces behind it, almost like a vacuum tube.
“And you can see there is a tunnel here going on it and it just looks kind of strange.”
The picture in question was snapped by NASA’s Spirit rover, which has been exploring the surface of Mars since January 2004.
The photo of “alien technology” was snapped on March 2, 2004, on Martian Sol 413.
In another section of the NASA photo, Mr Waring claims to have found an alien skull and face.
He said: “This is actually a face on a face. Maybe you get that? Why would they do that?
“Well, they’re higher thinkers probably or they just might not be higher thinkers.
“They might be a culture that believes this is art – that the most beautiful thing in the world is a face and so maybe they did that.”
Mr Waring’s bizarre claim sparked a wave of comments from UFO enthusiasts who believe aliens live on Mars.
Randall Tufts said: “Scott, the face on a face looks to be two different mediums like two different statues that fell close to each other.
“I totally agree with you on what you see. Life has existed on Mars and maybe still does, my own opinion.”
The most likely scenario however, is that Mr Waring has fallen for the effects of Pareidolia – a trick of the mind which causes people to see faces and patterns where they do not exist.
Fames astronomer Carl Sagan suggested in 1995 the effect is an evolutionary mechanism, evolved to help people better distinguish friend from foe.
NASA explained: “Pareidolia is the psychological phenomenon where people see recognisable shapes in clouds, rock formations, or otherwise unrelated objects or data.
“There are many examples of this phenomenon on Earth and in space.”
