Is there life on Mars? A photo of a rat on Mars was captured by NASA’s curiosity rover in 2012, and is now making the rounds online. The only catch is it’s actually a stone that resembles a rat.

That’s not stopping believers out there of life on Mars. One has even gone on to create a whole Twitter account for this remarkable stone that resembles a rat. This Mars-like stone already has a Twitter account @RealMarsRat which has garnered 475 followers in less than 2 days. This “rat” is also active in the social networking site as it had tweeted 76 times already and interacts with its followers.

The photo which started all the online buzz offers a panoramic view of the planet’s surface seems to reveal what looks like a “Mars rat”.

"It's a cute rodent on Mars. Note its lighter-color upper and lower eyelids, its nose and cheek areas, its ear, its front leg and stomach," Scott Waring wrote at UFO Sightings Daily back in December. "Looks similar to a squirrel camouflaged in the stones and sand by its colors."

In an update to that post, Waring hypothesized the possibility that NASA flew the rat/squirrel to Mars secretly, as part of an experiment testing out the Red Planet's ability to support life as we know it.

"Why would they not tell us about it?" Waring wrote. "Because the squirrel would be expected to die eventually and that would get PETA [People for the Ethical Treatment of Animals] to fight against them in a court of law."
