I really do not understand the topic title.
However, I am willing to bet that Mars' orbit was shifted a long time ago. I am also betting that it is older than Earth. What's beyond Mars? An ASS'ROID belt. What did all of those rocks used to be? Probably a planet that blew up because when GTA4 was released there it couldn't handle so much awesome, shifting Mars' obit and screwing things up. There could have once been life on Mars. Likely not intelligent life, but life nonetheless.
By the way, I am not a GTA fan. I am making fun of people who thing GTA 4 is the second cumming.
