Well, one UFO claims to have answered it, saying he has spotted bizarre alien creatures on the surface of Mars.
‘Alien creatures’ found by Waring on Mars
Scott C Waring, who runs ufosightingsdaily.com made the outrageous assumption after finding what he claims are a pair of odd-looking crustacean-like creatures in and among rocks in one of the latest images to be beamed back by the NASA Opportunity Rover droid.
He posted a picture taken by Opportunity on his website ufosightingsdaily.com, saying they appeared similar to scorpions or shrimps.
In a blog entitled “Two Animals Found On Mars Surface In NASA Rover Photo, Oct 2016,” he wrote:
The ‘alien creatures’ in a closer view
“I found these two shrimp-like crustacean next to each other in a NASA Opportunity rover photo.
“They both appear to have an exoskeleton much like shrimp, crabs and insects have.
“In the desert here on Earth, we have several types of crustaceans, one is the scorpion, an animal that can survive in an extreme environment that most other life forms could never survive.
“I think that is what we found. A Mars desert crustacean creature that is just trying to survive with its family.”
“Or perhaps the scaled outer shell of its body like a shrimp has?
Also the tail is lifted in the air, because you can see its shadow below it.”
Mr Waring’s so-called discoveries are the latest in a long list of animals said to have been found on Mars by alien chasers, including a bear, monkeys, giant worms, crabs and even a scorpion.
While, some have resembled the creature more than others, scientists and NASA dismiss the finds as the result of pareidolia.
This is a phenomenon when the brain tricks the eyes into seeing familiar objects or shapes like faces or animals in textures or patterns, such as clouds or rock surfaces.
