Final proof aliens exist? Nasa photos show ancient Hieroglyphs carved into rock on Mars
They even believe they may have evolved alongside us.
But sceptics argue the so-called discoveries on the images sent back by the rover – a 4WD droid which is exploring the Martian surface – are just textures in rocks.
They said people are being tricked into seeing familiar objects, such as writing and faces, by pareidolia – a phenomena that causes the brain to interpret what they eye sees in patterns an d textures as familiar things.
On top of this, researchers often manipulate the images, such as in this case, where the ‘writing” has been darkened to bring it out, they said.
One viewer posted on UFOsightings daily after seeing the images, which have been uploaded to YouTube: “If you zoom in on the original you can see the small boxes that appear to be pixels that make up the photograph.
“It appears to be those boxes that are outlined in this picture to make it appear like writing.
“I read an article that talks about how these photographs, when taken from the original version and reformatted to jpegs, end up looking like this with these small boxes.
“It’s difficult to tell if it’s a conversion issue or if it’s simply something someone highlighted in order to create a specific perception.”
The “writing” is the latest in a series of anomalies such as statues, fossils and even “aliens” that UFO hunters claim to have found in the pictures.
Other newer ones include something that it is being suggested is like a Mayan statue, and even remains of buildings and a crashed UFO.
Some people are convinced by them.
Scott C Waring, editor of UFOsightings daily wrote on his website: “The carvings do look very similar to ancient Egyptian carvings.
“This is a monumental discovery, one that archeologists around the world should be taking a closer look at.
“A written language from another planet, its the final straw that will reveal disclosure. This is what we need to find more of.”
But Nasa says although the rover has found evidence of water flows on the surface of mars – one of the requirements for life to start – there has been no evidence yet of any life being present on the Red Planet.
