The idea is the same, though. God's like the Wizard of Oz. Religions are laid out with these logical fallacies and unprovable "facts." They are all the same. It's a template. Believing that there was a Creator because science hasn't advanced enough, yet, is not firm ground to stand on. We come down to believing in God because we throw up our hands and say, "Well, I don't know what else would explain how we got here." There are all sorts of possibilities, and even the ones that include God don't at all include the God that you worship every Sunday (unless you worship Nyx and thank her for hatching the golden egg or something). There could be a supernatural explanation for creation and you'd still be totally wrong about what you believe.
God has revealed Himself to us over and over again, it's all through the Bible.
Still, you are not alone in your doubt. John 20:24-29
