I'm not claiming that I can prove no God could possibly exist. My position is that belief should be proportional to evidence. If someone claims that an all powerful, all knowing, perfectly good God exists, they need to provide evidence for that claim rather than shifting the burden onto someone who remains unconvinced. Arguments from ignorance, low probability, personal experience, suffering, or the existence of the universe may raise interesting questions, but they don't automatically establish a specific God. Until sufficient evidence is provided, saying “I don't know” is more reasonable than treating an unanswered question as proof of God.
