Universe

Given this is a site about logical fallacies and not physics nor theology, I will assume you want us to evaluate the question for fallacies.

"What was here before the universe?" 

This is begging the question that 1) there was something 2) there was a "here" and 3) there was a "before" - lots of assumptions that don't make sense without time or space.

"Who created it?"

Again, classic question begging. The question implies it was "created" and further, created by a "who" rather than a "what".
