mars was inhabited by intelligent life millions of years ago. something happened and it got fucked up, likely nuclear war or disaster. there was an exit strategy and they bailed, some even say it was the early human civilizations. once earth was inhabitable they looked on after it, hoping we wouldnt repeat the sins of the past. they constantly watch our nuclear assets and readiness to prevent us from destroying ourselves (again). its past us stopping us from being retards.
