: According to the latest cosmological theories about the origin of the universe it appears that the universe is completely self generating.

Hmm. "Theories" and "appears" do not compute. In other words, these theories are just that -- theories. They don't "appear" at all! There's no observation of them.

: All the forces required to start the universe can be described mathematically (of course)

Mathematical explanations do not prove the existence of something. Why are none of these theorized things observed?

: and there is no longer a need for a supernatural force to get the process in motion.

Are you sure? You haven't demonstrated this at all.

: Physics simply doesn't allow room for a supernatural force in the universe as we know it, and nothing can happen which is outside the laws of physics.

Tell me -- why is it that the science of physics exist? Because people want to think and reason about and examine things. But where did reason and the laws of physics---both nonmaterial realities---come from? Nonmaterial reason could not exist without a nonmaterial Person. Only persons reason; things do not reason. Reason and the laws of physics cannot account for their own existence. God, however, accounts for them both.
