Okay, so, I could write a big long post explaining why that probability statement is invalid (and there are many reasons that have been somewhat covered so far, and are well covered in Inertia’s link), but I won’t. Instead, I’ll just state that if a god created us, and the rest of the universe, and we’re the only life in it, that’s a whole lot of wasted space, just up there to look pretty. Why do planets exist around other stars, if a god made it? Any reason other than “to give astronomers something to look for”?

Really, I think it’d make much more sense for a deity only interested in humans to put us in a snowglobe-like enclosure, rather than this gigantic universe, billions of light years across.
