Would you prefer to have a belief in God?
Alternately, what type of evidence might persuade you hold such a belief?
Yes, I would prefer to believe in God. I'm only agnostic because I have to be, not because I want to be.
As for evidence, I've pretty much given up hope that any concrete scientific/historical evidence in favour of any religion will come to light. I'd be satisfied with a personal spiritual experience.
