text: This is like asking, "What does blue smell like?" Blue is not in the category of things that have odor, so the question itself is flawed. In the same way, God is not in the category of things that are created, or come into existence, or are caused. God is uncaused and uncreated - He simply exists.  How do we know this? Well, we know that from nothing, nothing comes. So if there was ever a time when there was absolutely nothing in existence then nothing would have ever come to exist. But things do exist. Therefore, since there could never have been absolutely nothing, something had to have always been existing. That ever-existing thing is what we call God.
