UFO Blogger reports a "thigh bone" has been found on Mars, but if you ask alien hunters, it's actually an "alien thigh bone."

NASA's Curiosity rover captured an image of the object, which looks like a femur, from its MastCam on Aug. 14, according to the Huffington Post.

UK's Huffington Post is saying it is not a thigh bone, though NASA hasn't confirmed or denied that the object exists.

But UFO Blogger commentators truly believe there is a possibility the new find is actually a bone, according to UK's The Mirror.

"We know that it's very likely that Mars had life and that it's again possible that life evolved into large creatures that could have left fossils and bones behind," one user wrote.

This isn't the first familiar object to be spotted in outer space. Just a couple of weeks ago, a "face" was found on a comet.

Additionally, NASA last year dismissed a found object on Mars as nothing important.

"On Mars, as on Earth, sometimes things can take on an usual appearance," NASA wrote last year after a shiny rock formation resembling a car door handle or hood was spotted.

What do you think the object is?
