Global space agencies and scientists have spent billions in the search for signs of alien life on the surface of Mars, but according to alien hunters, it may have been staring them in the face.

A video posted by a self-styled paranormal investigator claims to have identified the skull of a giant alien or Sasquatch simply lying about on the surface of the red planet.
The strange object was spotted in images beamed back to Earth by Nasa’s Curiosity Rover, which has been trundling around on Mars since 2012.
YouTube alien hunter Paranormal Crucible spotted what they claim is an alien skull lying on the surface of Mars. They said the object was ‘obviously alien in nature’ and appeared to resemble the remains of a ‘Sasquatch’-type creature

Other bizarre claims include a mouse, various faces, including that of God’s, and even an Egyptian sarcophagus.
NASA has not yet replied to a comment request from MailOnline.
Although we’re not completely convinced by the ‘skull’, we will let you decide.
Writing under the video, they said: ‘Strange artifact found by the rover, appears to resemble a large skull, obviously alien in nature, could it be the remains of a Sasquatch or a bizarre Martian creature?’
The image in question (pictured) is the latest in a string of bizarre claims from alien hunters that believe there is definitely life on Mars. Other recent sightings include a shark, a crucifix, a mouse, the face of God and even an Egyptian sarcophagus
