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

[RobbyPants]

beginnings only make sense were time is linear like the our cosmic time line that's unidirectional and unstoppable. according the big bang cosmology theory: time, space, energy, matter began 13 billion years ago. if God caused the universe, by necessitate then He has access to at least another time dim. or it's equivalent.

Exactly. Now, prove that the universe began. No one witnessed its beginning. For all we know, the universe as we know it began with the big bang. How do you know there isn't some portion of the universe that exists outside of time that we cannot observe? Now, yes, this is speculative, but so is God. At the end of the day, I'll say "I don't know" when you asked me how it started, but you'll smugly say "God", like you've somehow solved the problem.

While the notion of the universe having no beginning may seem stupid do you, remember: you're totally fine with a god that has no beginning. You're just picking an unsupported "solution" to the cosmological argument that happens to match the narrative you already have.
