Neither do I. I'll take the risk of doing a real-world analogy, which can be touchy when speaking of religion, but being an atheist, I think there is no god. When I say that, I imply "in our universe". If, when the bing bang started, another bubble universe was created at the same time, with which we cannot interact (and which can't interact with our universe), and a godlike being took charge of "his" universe, my real-life worldview wouldn't be invalidated, because its existence would be improvable and be functionnaly meaningless in our reality.
