David Martines, a YouTube user, had used Google Mars to find a shape of something that wasn’t typically identifiable with normal things such as rocks, and he suggested that the thing he found on Google Mars could be something made by someone, whether that was made by aliens or us humans. Google Mars is something similar to Google Earth, but it’s for Mars. I’m quoting Wikipedia’s exact text on Google Mars:
Google Mars was at first an in-browser version of Google Maps which provides a visible imagery view, like Google Moon, as well as infrared imagery and shaded relief (elevation) of the planet Mars. Users can toggle between the elevation, visible, and infrared data, in the same manner as switching between map, satellite, and hybrid modes of Google Maps. In collaboration with NASA scientists at the Mars Space Flight Facility located at Arizona State University, Google Mars provided the public with data collected from two NASA Mars missions, Mars Global Surveyor and 2001 Mars Odyssey.
David Martines called the thing as Bio Station Alpha. The video below shows David Martines’s discovery of a strange object on Mars through the use of Google Mars.
Update: Unfortunately, the video had been removed by this YouTube user!
