My question for the forum is this: If you have used reason, logic, science, whatever, to liberate your mind from the JW faith, why haven't you also let go of God?
That question works for me. Once I freed my mind from the misleading doctrine of the JW's, I had to know what else was wrong with the Bible, the supposed basis for the JW religion. Then I had to know what was wrong with Christianity, and belief. I went through this very similarly to the way you ask it so straighforward.
But despite my own confidence that there is ample evidence of a world without need of a creator, a universe without need of a creator, I also try to understand that many people have gained (through evolution) a need to believe. It's not as simple as saying you cannot prove a teacup is not orbiting the earth, it's about equal to the vast majority of humanity believing and proclaiming the teacup in orbit and suddenly, virtually in a single generation, rumors start that the teacup isn't there. You can't expect everyone to abandon their beliefs in the teacup.
