There appears to be a pretty big gap between "life" and "intelligent life". In our case, it took between 3 and 4 billion years to go from "life" to radio communications, etc. At any rate, according to Stuart Kauffman of the Santa Fe Institute, simple life should be pretty abundant since it's only a matter of of having a diverse enough collection of molecules. Once a threshold is crossed, autocatalysis or self-organization is nearly inevitable. So simple life is pretty much at home in the universe.
It's unclear whether it's inevitable to eventually evolve into intelligent life of the sort that could send communications to other star systems. There's self-organizaiton and natural selection, but much also depends on chance and contingency. What if the asteroid that wiped out the dinosaurs had missed?
