Option 1 is the least likely. What is a god? Where did the concept of a god come from? Is it that difficult to understand that God is nothing more than a creation of the human mind?
Option 3 is sort of the most likely. We just dont know yet. Since there is nothing we can see past the big bang, we dont know whats beyond that.
If you ask me, what makes sense is that the universe/s are chaos. Randomness, existance and non-existance, something and nothing. At one point one of these tilted over just so slightly and it led to the creation of the universe. Once matter existed, the so called laws of the universe or the laws that tell us how objects interact with each other came into play.
The details are always just something we must ponder upon, but i can garantee you that a "God" in the way we humans imagined it is certainly not responsible for it. That much is certain.
