A UFO expert claimed to have spotted a couple of alien artifacts on Mars after going through the photos taken by NASA’s Curiosity rover. According to the UFO expert, one of the images featured a leg that appeared to be mechanical in nature.

Scott Waring of ET Data Base came across the images after browsing through the online gallery provided by NASA’s Mars Curiosity rover.

One of the photos that Waring came across was taken by the rover on SOL 2483, which is equivalent to the date Aug. 1, 2019, in Earth time. The photo was taken using the rover’s Mastcam and featured a black-and-white image of rocks on the Martian surface.

Interestingly, an object located at the center of the photo looked surprisingly similar to a boot. Waring initially speculated that it could be a leg from a broken statue. However, after analyzing the photo, he concluded that the object came from an ancient robot that lived on Mars.

According to Waring, the object had mechanical features that suggested it was a robotic leg.

“You can see the foot area with a lower tread and thick heal on it, the upper part of the boot-like foot,” he wrote in a blog post. “The thing that convinces me about it being a robot is that if you look at the leg attached to the shoe, you will see hinge areas that a robot might have.”

Aside from the mechanical leg-like object, the UFO expert also spotted a portion of a wall on Mars. He came across the image in a photo taken by the Curiosity rover on SOL 2480.

The photo featured an image of the Martian landscape. Across the surface, objects that looked like brick walls can be seen sticking out from the ground. Based on their appearance, it seemed the walls broke off from a much larger structure and were buried by Mars’ extreme dust storms.

According to Waring, the objects reminded him of thee walls commonly found stretching across the hills of Scotland and the United Kingdom. He noted that the walls in the photo may have been built by hand by the previous inhabitants of Mars.
