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

Can't have infinite regression since by definition nothing could begin, nor can have a random generator (no intellect), nor could there be God², God³, etc.

You are trying to apply THIS universe's logic to something you have claimed is OUTSIDE the realm of this universe. You have no way of knowing that said logic is applicable anymore. It might be, but it also might not be. I thought I made this clear already, you can't discern the veracity of any statement you make about something outside our universe since all and any possible frameworks to approach the issue with are no longer guaranteed to apply. You have no hope of necessitating such a thing's existence when you have no means of producing reasonable certainty.

If there's one thing I've learned about all of these theistic arguments that require ad hoc explanations to keep them afloat, it's that theists treat all of these ad hoc explanations as if they exist in a vacuum, never considering the consequences of that explanation beyond the current hole in the argument they are attempting to patch.

They're just on a sinking ship, and every time they plug one hole, another one pops up, because they never consider the big picture and just seek to justify their preconceived beliefs. It would be entertaining if it wasn't so goddamn frustrating to watch.

This is what happens when people with faith-based beliefs try to justify their beliefs with logical equations. Logic and faith are inherently opposed to each other, so when they mix, it's like oil and water. The best theists, in my opinion, are those that admit and embrace what it means to have faith. Strangely, they also tend to be very logical on just about everything else.
