Nothing! The idea of the universe, or anything coming to be out of nothing is worse than magic.

Any system of thought that assumes causation is a necessity leads to an infinite regress.

Assuming that causation is not necessary may be counterintuitive, but many things in physics are counterintuitive.

So you can choose between counterintuitive physics or a logical absurdity.

Any system of thought that assumes causation is a necessity leads to an infinite regress.

This statement is not true beyond the point of singularity of origin of the universe. If you believe what you said, please regress cause to the step "one point" prior to the universe coming to be. I will not ask you to infinitley regress....just that one step.
