Ahhh but I mean what happens before the universe began is beyond the realm of science (at the present time). Religion and science are not two sides of the same coin.
This is where is disagree a bit, but thank you for bringing this point to light. Science is just a method for testing ideas. Anyone saying it is anything other than that is selling something. You should see and hear warnings. “Trust the science” goes against the scientific method. Ideas should be tested. If they aren’t you end up with Religions. The Universe had no beginning, much the same as believing god had no creator. Existince is a dance between density and entropy.
