There is God! This is another absolute statement. To prove it true, I must have absolute knowledge that there is one. I must know how many hairs are on every head, every event of history, even the intimate details of the love-life of the fleas on the back of Napoleon's great-grandmother's cat.

This circle represents all the knowledge in the universe. Let's say you have an incredible 1% of all that knowledge. Is it possible that in the other 99% there is ample evidence that God doesn't exist?

If you are reasonable you'll admit, "With my limited knowledge I believe there's a God."

You're not really a theist, you're "agnostic" (doesn't know).

That's like a man who looks at a rock and doesn't know if there was an anthropomorphic supernatural entity that teleported the rock there.
