Many theoretical physicists use their imagination in order to have deep thought about the universe and its establishment, yet it rarely leads them to a "God." Are you saying in order to believe in God, you have to have an imagination--just like you would if you believed in Santa Clause? You have to have faith to believe in Santa Clause as a kid, but once you realize that it was just a story that old people told you when you weren't old enough to understand how things really worked, it probably wasn't that hard to disbelieve. My view is the same as yours ("I don't have all the answers, and I'm okay with that"), and I have a pretty good imagination, but none of this leads me to any belief in a god that oversees our moral aptitude. If your definition of God is simply all that you can't understand, then I suppose I'd submit to that philosophy, but most God-fearing people don't stop there. May I ask, are you a practicing member of a religion?
