Are these grainy photographs proof of mysterious, hidden alien structures on Mars?
Probably not, but it has not stopped self-proclaimed alien and UFO 'experts' from claiming a series of images taken by NASA are the clearest evidence yet of a network of complex Martian structures throughout the red planet.
The 'experts' claim the structures were built by aliens who constructed them in such a way as to hide their presence from visitors from other planets.
Sandra Elena Andrade, one such 'expert', runs a YouTube account where she uploads a series of videos with increasingly outlandish claims of evidence of life on Mars and beyond.
Using images from Google Earth, the alien hunter points to a number of regions on the red planet - arguing they clearly show
structures built to house aliens.
Members of the UFO community then claimed scientists at NASA had attempted to hide the structures with photoshop.
Another YouTuber, called Dahboo77, also uploaded the video and argued it was the best proof to date of structures on Mars.
He said: "Every time an amazing discovery is made on Mars, They quickly tell the sheep it is a rock or shadow!
"Time and time again, They try to make excuses for the objects being discovered all over Mars.
"This time, they are not fooling anyone by saying its just rock formations.
"No doubt, some of the small minded out there will buy NASA Lies until the Great Deception!
"But for those out there with an open mind, And that know we are being lied to, This find speaks volumes!"
The claims come after a retired naval infantryman, who uses the pseudonym Captain Kaye, claims he spent 17 years on Mars protecting human colonies from Martians.
