A self-proclaimed alien-hunting expert believes he has spotted an ancient jet engine lying on the surface of Mars. He says it is proof that Martians existed and had technology far superior to our own.

Scott Waring of ET Data Base spotted the “engine” while trawling through photos snapped on the Red Planet by NASA’s Curiosity rover, which has been trundling around Mars’ dusty Gale crater for nearly eight years.

The image was captured on August 30, 2014, which was the rover’s 735th Martian day, or sol, on Mars. In a blog post published this week, Waring highlights a peculiar pattern in the material on the surface and claims that it resembles modern-day jet engines. (RT)
