13. Jelly donut
Apparently aliens are partial to sweet treats, too. But the weirdest thing about this apparent image of a jelly donut is that one day it wasn’t there, and then 12 days later it was. Did NASA’s Opportunity rover miss a careless alien dropping it as it passed by? One concerned citizen even launched a lawsuit against NASA, claiming that they were not investigating this donut-shaped proof of life properly.

Scott C. Waring, a self-titled “alien expert” from Taiwan, believes that this image depicts a giant scorpion scuttling across the surface of Mars. The intriguing image was captured by the Curiosity rover in September 2015, and it’s left quite the sting in the tail.
