From prehistoric pyramids to secret military bases, there's not much conspiracy theorists haven't seen on Mars. Now, in their recent weird finding, alien hunters say they have found a mysterious 'facehugger crab' on Marian surface. Since the photograph was shared on Facebook, a lot people have said it looks like the facehugger monster presented in the 1979 film, Alien. The 'crab' can be seen in a photo captured by the Mars rover Curiosity which displays a formation that appears a cave mouth on the red planet. The photo was captured by NASA in July but lately appeared in Facebook group 'Journey to the Surface of the Mars', who has the motto: 'They will not tell the truth about Mars'. Director of the Centre for SETI Research, Seth Shostak said this is possibly a case of pareidolia.
This is the psychological reaction to seeing faces and other important and everyday objects in random stimulus. It is a kind of apophenia, which is when people see shapes or connections in casual, unrelated data. Human eyes can detect faces inside their environment and it helps them recognize friends in a crowd, or stuff like that. Scientists also say that we have a habit of to use this capability to 'enrich our imagination' and recognize important shapes, even when they're actually not there. Seth Shostak said 'Those that send [images] to me are generally quite excited, as they claim that these frequently resemble something you wouldn't expect to find on the rusty, dusty surface of the red planet. It's usually some sort of animal, but occasionally even weirder objects such as automobile parts. Maybe they think there are cars on Mars.'
He also said: 'Recognizing a crab in a landscape jam-packed with wind-weathered rocks is no more shocking - nor more important - than seeing a winking face in a semi-colon followed by a parenthesis.”
