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

so we have this situation: going back towards the big bang, inside a second the physics laws breakdown which includes our cosmic timeline that has a component of cause and effect. a causal agent before this timeline wouldn't need a beginning. the universe created by an eternal God is at least a reasonable consideration.

Whoa whoa, you're still making a hell of a lot of assumptions there, one of which being that the state before the big bang was just one big "no rules" setting where an eternal being is possible. You don't know that; for all you know, there was a separate set of cause and effect laws in place within a dying universe just before its big bounce into ours.

Also, even if we accept your premise, you're still leaping to god and eternal, when all you can really say is "being," and even that is assuming consciousness where none might be found.
