Mars is getting contaminated in the near future, whether we find life on it or not. Whether we collectively want it to be or not. Given the ever-decreasing cost of launches into space, the increasing access to small satellites, I think suspect it's inevitable that some collection of Earth microbes will get a ride to Mars within the next century. Whether it's a motivated team of grad students, an obsessed billionaire, or a small nation that doesn't decontaminate its lander before launch, it's going to happen.

I don't follow why life on another planet would have any bearing on the idea of a Monotheistic God.

This is why I kind of admire the biblical myths; their selective details and smoky metaphors have proven incredibly resilient to new truths, and invite so much speculation.

The garden of eden could be in some far flung galaxy, from which we “life”, were expelled as microbes, thanks to the sins of relatives we wouldn’t recognize. The rib of Adam could symbolize the arbitrary evolution of sexual reproduction from asexual origins. The forbidden fruit could represent some inevitable nuclear holocaust spurred on by some intra-species conflict, which prompted life to be cast out and begin on another planet. Something unique about our shape of life means that we’re stuck in a cycle of destructive evolution that cannot be saved from itself, excepting for the divine intervention of some less imperfect shape of life.

Anyways, I’m rambling! I hope this sparks somebody’s theological-scifi bug and produces a mildly entertaining narrative in somebody else’s head. :)

It makes God's ultimate and unquestioning perfection in creating the Universe called essentially into question. If there is life on Mars, then it's no small leap to think there's life outside of the Solar System. What place then do we, as God's children have in the Universe, and in God's grand plan?

Stuff like that.
