Alien enthusiasts claim to have found compelling evidence of intelligent life once existing on Mars.
UFO conspiracy websites are posting this image which some allege shows three mile-high towers built in a line on the surface of the Red Planet.
The anomaly, which equally could just be eroded rock formations, was first highlighted by YouTube channel Mundodesconocido in a video.
According to channel these discoveries could have been built by intelligent extraterrestrial beings. It said: “Investigating on some Mars images, we have recently found a row of huge towers located in the Martian area of Terra Meridiani.
“Due to their peculiar features, we believe that they have an artificial origin.
In the following video, we will show you all the amazing information and evidence, as well as animated 3D models that will allow you to evaluate correctly the information we propose.”
This news has been picked up on by UFO blogger Scott C Waring.
He posted on website ufosightingsdaily.com: “There are a whole planet full of buildings and artefacts to be discovered on Mars.“
It is one of the latest so-called discoveries which alien chasers hope are the remains of walled cities and villages on Mars.
But scientists from NASA, who have a number of rover droids actually exploring the Martian surface claim they are no such thing and are just rock formations.
They say all these alleged discoveries are the effects of pareidolia – a phenomenon when they brain tricks the eyes into seeing familiar objects such as faces or animals shapes in patterns like clouds or the textures of a rock. In other words, sometimes people are seeing what they want to believe they are seeing.
