I totally think its possible to believe in "sky daddies" and be considered sane. The more and more we learn about the universe and everything in it, the more we realize that we don't know anything. For example, take the big bang theory. We are supposed to believe according to the big bang, that a bunch of dust and gas were densely packed into a single point and one day it all started to expand outward randomly. This notion of accepting theories and science in general is no more sane than accepting the concept of a God or multiple deities. Science can validate the belief in a God and can also deny the existence of said presence. But in the end it comes to whether or not you want to reduce existence to nothingness and random probability or you you can say that something else is the driving force behind the world and universe around us.
