The common response you'll get for "Who created God?" will be something like "He's beyond our understanding, so we don't question where He came from because we will/can never know". It's faith as Pedobear cited.

Right now what believers suggest is since we cannot understand the universe i,e it is beyond our understanding, and because Science cannot (as of this moment) explain it, God created it. So, if the universe is beyond our understanding, why are you questioning it's existence? I can just as easily hypothesise the existence of a gigantic spaghetti monster that hides behind Jupiter in such a way that we cannot track it, and you cannot disprove me. But we know it's false, simply because it's so damn improbable.

You may be interested in The Flat Earth Society that advocates biblical descriptions of the world by turning the modern scientific tools onto themselves (Einstein will rise from his grave if he read what they did to his relativity). Marvellous minds in the wrong can of thoughts. Seemingly convincing but fallacious at its core. Read and don't fall into their trap. It looks real. You just have to know where it's wrong. Enjoy.

Don't worry, I have no danger of falling into that trap. Stupid really, I was like when I saw that website. Those people are still in their caves, scratching on their walls with blunt stones.
