Just to be clear, I don't have any idea whether or not there is intelligent life on other planets. It's one of those questions that are unanswerable. There is no information available to us. What I did say is that we know that intelligent life has appeared at least once, so it is possible that it appeared more than once. More likely than the existence of gods, for which we don't have the same sort of hard evidence that we do for the possibility of sentient life evolving.
