Is there an alien 'coffin' on the Red Planet?

New York, Dec 29 : Hunters of unidentified flying objects (UFOs) have spotted an object that looks strangely like a coffin on the Martian surface. In the video posted on YouTube, spotting the alien coffin is difficult to view at first but a closer inspection reveals the intriguing anomaly, the Inquisitr reported. "This stone object looks like a coffin," researcher Scott Waring of the UFO Sightings Daily was quoted as saying. It looks to be about one metre across and a foot-and-a-half high. According to Waring, the object may simply be a stone formation but wonders if NASA could turn the Curiosity rover around and take a closer look at the "coffin".
