I think once you understand evolution, you know that life is a natural physical phenomenon, and a statistical likelihood. If a system starts self-replicating, that system will naturally become more successful over time. If it doesn't, it will be replaced by more successful variations.
It would be pretty absurd to think that ours is the only planet on which self-replicating organic systems have sprung up. Life probably spontaneously forms right here on Earth all the time, if it can survive long enough without getting eating by a bacterium or something.
