Mars may have been named after the mythological God of War, but there’s no actual battle, specifically alien combats, that actually happened on the Red Planet.

This is why it is highly unlikely that the perfect spheres previously captured by NASA’s Mars Curiosity rover are cannonballs, but these remain to be some of the most significant discoveries on the planet that could prove life might have existed there.

According to a report, the balls are actually river pebbles nicknamed “blueberries” by NASA scientists. The blueberries were initially regarded by alien theorists as actual cannonballs and with it a crazy theory as to why Mars has become a dry and barren planet we know it to be now.

According to UFOlogist Scott Waring, the rock is too perfect to not be regarded as an actual cannonball. Waring said that the rock is the same size as a softball and that it is made of actual metal.

Waring pointed out that the weapon fragment sits perfectly on supposed projectile of the blast and that it explains the “wreckage” on the Martian surface. He also pointed out that these fragments just goes to show that there was indeed an ancient civilization that once lived on Mars.

“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's surface,” Waring said in a post.

For this discovery, NASA gave an actual reply, explaining via the official Curiosity Twitter account that, “The round 5mm concretion I found (L) contains calcium sulfate, sodium + magnesium, making it different from the hematite-rich 'blueberries.'”

The earlier blueberries were discovered back in 2004 by NASA’s Mars Opportunity rover. According to a report, the blueberries may not be actual alien ammunition, but the mystery involving how they were created could be alien in nature.

In perspective, these hematites are evidence that shows planet Mars was once a wet planet. "No matter what the exact chemistry of these spherules was to start, the fact that they're there tells us [that] a lot of liquid water moved through these rocks over time," Briony Horgan, a planetary scientist at Purdue University in Indiana, said during an interview.

The team studying these geological materials said that the blueberries are crucial in learning precisely how the hematites were formed and could give scientists an idea of how the planet, and in a way alien life forms, survived millions of years ago.
