Curiosity finds Ancient Wall and Drainage ditch up on a mountain on Mars
According to this video, Martian Archaeology was analyzing a NASA photo taken by the Curiosity Rover when he happened to find structures on the planet Mars which not look natural at all.
In the background there is a formation that appears to show an ancient wall and drainage ditch up on the mountain.
These artificial structures are new evidence that Mars was inhabited thousands of years ago by intelligent beings?
