An ancient cannonball was found on Mars, leading alien conspiracy theorists to reach the conclusion that there was life on the red planet and the civilization could be wiped out by war. A conspiracy site UFO Sightings Daily recently shared a video purporting to show what was very interpreted as a cannonball on the Mars.

The picture shown in the video was reportedly taken by NASA’s Curiosity Rover droid, which is currently exploring the surface of Mars and beaming back close-up images. There have been theories that there was once an ancient civilization on Mars that was wiped out by some alleged intergalactic nuclear war, which also destroyed the Martian atmosphere, making it uninhabitable. The reported discovery of cannonball has only fueled the theory.

Scott C Waring, the editor of website, said, “This metal ball is perfectly formed and about the size of a softball here on Earth. Guess what? That also matches the size of a cannon ball.” Waring added: “This projectile is sitting on the surface above all the wrecked stone structures around it.

“Fragments of a once civilisation is sitting scattered in tiny pieces around this cannon ball. “I do believe these balls and millions of others were deliberately shot at Mars from space all at once to destroy their atmosphere, burn it away. “What I mean is a large enough man-made meteor shower could strip Mars of its atmosphere and thus, destroy all or most life on the planet surface.”

British alien investigator Nigel Watson, author of the UFO Investigations Manual, however, rejected these theories. “It looks strikingly artificial but even on Earth large spherical rock formations have been created by natural forces,” he was quoted as saying by
