I must assume that you are either an agnostic or an atheist by reading your reasoning.
From your perspective thought, do you believe that there is intelligent life on other planets?
(I believe it.)

Not sure. I hope so. I love science fiction. We know too little about the chances of abiogenesis and the distribution of earthlike planets on those untold trillions of stars to make any more than a wild-assed guess. Inner planets tend to be the right size and G suns are fairly common. As another poster said the huge moon that we have may be a factor. How common is that? Hard to tell, but most moons are much smaller than ours in relation to their primary body. Then how many molecules are suitable to be a first replicator from which everything else can descend? We don't know. How likely is it for one to form in the most suitable conditions? We don't know. Lots of imponderables.
