The book to read about the secular vie of chances of life on other planets is Probability 1 by Amir D. Aczel.
The chances of conditions existing for life on other planets are almost certain. Whether or not God would actually breathe life into something there is another matter. I for one see no reason why not. And wouldn't it be cool if we do contact an alien race, compare our religion with theirs and discover they had a "Jesus" die for them too?
