Anomaly hunters scouring NASA images for oddities believe that a strange circular stone pattern found on Mars might be a sign of alien life.
The remarkably round formation was noticed in a photo taken by the space agency's Mars Curiosity Rover.
This discovery, however, is simply a circle of rocks that leaves the observer to decide whether it formed that way naturally or if it was constructed by an intelligent being.
To that end, advocates for the theory that ETs once called the Red Planet home propose that it could be the remains from an ancient structure, perhaps one that is buried beneath the surface of the planet.
Conversely, some skeptics say that there is a natural process that may have formed the circle by way of lava being shot from a nearby volcano and cooling in the round pattern.
