A UFO expert claimed to have found an ancient alien doorway on Mars through NASA’s photos. Interestingly, it resembled the other doorways that the UFO expert previously spotted.

The claims regarding the existence of an alien doorway on Mars was made by Scott Waring of the UFO-focused blog ET Data Base. Waring said he saw the structure while browsing through the photos taken by NASA’s Spirit rover.

In one of the photos, which featured two rocks on the Martian soil, Waring saw what appeared to be an opening on one of the objects. He noted that the opening almost had a rectangular shape.

Because of this, Waring speculated that the opening is actually a doorway to an alien house or structure. Based on the size of the rock compared to the rover, Waring estimated that the doorway could be about 4 inches wide and 6 inches tall.

According to Waring, the size of the doorway coincides with his previous discoveries of statues and carvings on Mars. Since they were about the same size, they may have been made and used by the same species of small alien beings.

Surprisingly, this isn’t the first time that Waring came across doorway-like openings in NASA’s Mars photos. Earlier in July, he spotted a doorway on another rock. Unlike his recent discovery, this one was bigger. Waring noted that the doorway was about a foot tall. In addition, based on the trail leading into or away from the doorway, Waring speculated that it is still being used by the alien creatures that built it.

“If you look carefully in front of the door, you will notice a used trail leading out of the doorway and over to the left,” Waring wrote in a blog post. “The trail looks like it’s been recently used, so whatever made that trail, still lives inside this doorway.”

Waring also said that the aliens intentionally made the structures look like rocks as a form of camouflage.

“It looks like a rock, but it’s not,” he wrote. “It’s an alien structure that is made to adapt to the Mars environment and to blend in.”

Spirit Rover Photo
This image from the Mars Exploration Rover Spirit hazard identification camera shows the rover's perspective just before its first post-egress drive on Mars. On Sunday, the 15th martian day, or sol, of Spirit's journey, engineers drove Spirit approximately 3 meters (10 feet) toward its first rock target, a football-sized, mountain-shaped rock called Adirondack (not pictured). In the foreground of this image are "Sashimi" and "Sushi" - two rocks that scientists considered investigating first. Ultimately, these rocks were not chosen because their rough and dusty surfaces are ill-suited for grinding. NASA/JPL/Cornell
