ALIEN hunters claim to have found the historic "final straw" of evidence that extra terrestrial beings exist claiming they have discovered ancient hieroglyphic-like carvings on Mars.
Nasa photographs, taken by the Curiosity Rover, apparently show the writing on a rock.
Footage of Nasa images, taken by its Curiosity Rover, show the writing on a rock, according to and alien researchers and conspiracy theorists who are convinced it proves there was once an ancient civilisation on Mars, much like those on Earth.
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.
