Well atheists always point to one or two "facts " and then ignore questions posed by believers or act like the questions are irrelevant. For instance atheists here were stating how its ok for a theist to believe God came from nothing but not ok to believe the universe sprang from nothing. well scientific theory doesn't allow for something from nothing. In the realm of the natural that is against all natural laws. God on the other hand lives outside the laws of nature so it doesn't apply
The thing is, saying that it came out of nothing doesn't help as we just don't know what it was. A good analogy would be that before the big bang, the universe was compressed in a suitcase. The thing is, what was outside of the suitcase?
We just don't know what happened. If I can sum up the theistic position:
-The Big Bang happened out of nothing.
-Something can't come out of nothing.
-Therefore, God caused the Big Bang.
We don't know if it was nothing, scientists like Hawking and Krauss have recently argued that the laws of physics and quantum mechanics could explain the Big Bang. It's only a theory and they don't know yet but I find that approach much more rational then creating a false dilemma and using an argument from ignorance. Was the big bang a singularity? Sure. Nevertheless, we don't know how it happened.
Furthermore, using that theistic approach serves nothing as you would have then to explain how God came into existence and as I said, special pleading doesn't work.
