Mysterious monument is proof there was once life on Mars.
Mars
Reconnaissance Orbiter took this photo of a monolith that was
discovered on the surface of Mars. This object even has the shadow the
revels that it is in fact standing upright. This has all the signs of
being a structure made by an intelligent being. How much more evidence
do we have to have before we are buried alive in it? With so much
evidence clearly there are powerful forces at work to keep all this
secret.
