Is There a Civilization on Mars?

An austrian astronomer wanted to dig massive trenches in the sahara desert, fill them with water top them with kerosene and then set them on fire. Or there was a french guy who asked money from the french government because he wanted to build a giant mirror which would focus sunlight and write messages on to the surface. And more aggressively, we actually sent a dedicated message to space from the seo observatory, this huge radio dish that used to be operating in perto rico. We sent a message out into space specifically for aliens, in a design, in a way we thought maybe they would be able to decode its sort of a pictogram.
