Where did the universe come from? Atheistic origin science has no answer.

If there is time outside of the universe then it may not work in the same way as it does within the universe. It may be possible that effect happens before or concurrently with cause - we simply do not know.

Further- if you are going to bring causality into the discussion then you have to address what God's material cause was for the creation of the universe. In your case you have God as the efficient cause but there would have to be a material cause. We have no examples of efficient cause without a material cause (although we do have examples of the reverse - material cause without efficient cause).

If God created the universe from nothing then that is outside of causality as we understand it and citing causality in your argument undermines your position that God did it.

the cosmological argument for God existence couldn't be used as evidence when the U. was thought to be infinitely old for that would mean an infinite regress of cause and effect transactions which would render a Causal Agent unnecessary. but now the theory of relativity with it's space-time theorems add-ons establishes the U. had a beginning. Therefore the natural realm is limited to a first-order infinity and necessitating a first cause, that's what the scientific evidence shows (yes evidence).
