UFO Sighted in Mars? Does NASA Photo Show 'Alien' Flying Saucer?

People claim that there seems to be an unusual, circular object on a photograph of Mars taken by NASA, indicating a possible alien sighting.

NASA's Mars Curiosity rover seemed to have accidentally spotted something strange in one of its photos which look like a "crashed flying saucer". Initial inspection said that it is just a massive odd rock, but enthusiasts want the space agency to do close examinations to prove that it may actually be an alien object.

UFO hunters continuously examine a number of photos taken by NASA to prove that "odd objects" give other planets the possible evidence of life on Earth. Streetcap1 is one of the leading UFO spotters in social media and uploads their 'evidence' on Youtube. Even though they wanted to call this object UFO, it is not possible since it is not "flying" and simply standing atop a hill on the Red planet. They find it odd that a 'window' is sitting peacefully in that area, as reported by Inquisitr.

They entitled the video "Martian Hill Anomaly" where a rocky hill is protruding in the landscape. They observe a dark form on top of the hill that was kind of taper off the surroundings. They are considering it as a rock, but it may be very massive. And they seem to be windows on it. When did rocks have windows, anyways?

The thing that makes the unidentified object more interesting is the obvious fact that it doesn't fit in with the rest rock since it is darker with a seemingly familiar spherical shape - a flying saucer. Even UFO Sightings Daily owner Scott Waring said that the 'disk' looks like it's been made of the same materials as its surroundings. It could either be a landing flying disk or a building built in the area purposely to provide a better view. But Waring is famous for having imaginative alien speculation so his statements aren't that reliable.

Skeptics are trying to be unbiased as much as possible but they said that the evidence of alien life on this photograph is too thin since the disk could be another photoshopped image. Other think that the disk appears to be an "enlarged view of linear sand dunes" so it could be really anything we think of until humans confirm it once and for all in the next decade as they plan to visit Mars in person.
