You could probably say that the complex of the universe is beyond our comprehensive abillities as well so that's kinda 50/50
What created the universe? Big bang. What created big bang? God. But what created God? No matter what, it will always lead to the question of what created what. But what if something may simply not be created from something? What if some things are just infinite? God could be infinite but the universe may be too. So it's really just what you choose to belive.
