If it's not different, it suggests that you believe the chance of the existence of god is equal to that of there being advanced alien civilizations with technology beyond our comprehension. Neither does anything in the way of real explanation, but if you believe that advanced alien civilizations are likely to exist (which is a fairly defensible argument based on things we DO know) or have existed (depending on how far away what we're observing is), the likelihood is quite different. Not that I'm saying it's aliens.
