One of the wildest claims of finding proof of alien life on Mars was recently revealed by an infamous alien theorist or UFOlogist.

According to Scott Waring, who runs the alien blog, he has found absolute proof that there’s an ancient alien city on the Red Planet. In a post, Waring used a photograph that showed some visibly odd shapes that seem to create a solid, city-like structure.

“Here are some pyramid-like structures on Mars. There are over two dozen of them and it looks like it might have been an ancient city long ago,” Waring said.

The UFOlogist said it was YouTuber Sandra Elana Andrade who first released the photos which were released via Google Maps. “The edges of the structure are absolutely perfect. This incredible attention to detail could only be attained by intelligent design,” Waring further pointed out.

In the initial video, the structures were actually described as the “terraces of Mars” because of its stair-like formation. However, the structure might actually have a scientific explanation as to how it was actually formed.

In a previous IBTimes report, some of the odd yet amazing structures in the Red Planet have been formed due to its extreme weather and weak atmosphere. An image of some “weird claw marks” taken at the Hellas Planitia on Mars and located inside a massive crater that’s said to be deeper than the Grand Canyon, for example, was explained by NASA to be “linear gullies” which have been caused by dry ice breaking the surface into blocky shapes before sliding down the sand dune. The lines are actually the carved path the dry ice creates as it slides down.

These kinds of phenomena are nothing new to scientists and NASA claimed that they have seen it in another Martian region although the lines are not as squiggly as the one taken by the MRO on Hellas Planitia.

Now, although the pyramid-like structures may look quite different from the marks on Hellas Planitia Canyon, it can be taken as a possibility that the weird structures on the Red Planet can actually be explained.

Waring, however, is adamant that what he saw is strong evidence of extraterrestrial life forms on Mars. “These structures are absolute proof that aliens not only lived on Mars but thrived in bustling cities such as this.”
