As for the OP, the same line of reasoning lead me to atheism. The questions asked of the JW faith and god weren't answered by another. Seemed too close to a compromise of logic and purpose, an easy way to settle for something familiar and comfortable rather than commit to the reasoning and search that began the exit.
That being said, I think there's no definite way to prove/disprove god. I don't find it uncomfortable to contemplate Spinoza's version or the ideas offered by eastern beliefs, what I know of them.
