Please provide, eh? The math breaks down at singularity.
"Science requests, "Give us one free miracle and we'll explain the rest." And the one free miracle is the appearance of all the matter and energy in the universe and all the laws that govern it from nothing at a single instant."
It's actually only religious apologists who insist that if God didn't do it, it had to be a miracle of the universe coming from nothing.
It's just a plain lie to mislead people about the science, to build a straw man of the science and drive people away from it.
There are many speculative hypotheses about where everything came from beyond the extent of our knowledge about the big bang.
They are all far more rigorously checked for consistency with known physics, than 'god did it'.
A few of them have found ways that the universe could have come from a nothing-like state, no miracles required.
Don't believe that those are the only alternatives to goddidit. It's a lie.
Don't believe they require a miracle either - they are constructed out of physics as we currently understand it, extended in speculation beyond the current limits of the evidence.
Goddidit is not constructed out of any of the principles of physics, and it specifically violates many of them.
Going from 'I don't know', i.e. 'the math breaks down at the singularity' to 'it must have been magic' is classic theist fallacy town - projected onto science and scientists as a straw man.
It's your mistake claiming there's a miracle where the math of General Relativity breaks down, not the science's.
Science doesn't say 'beyond that there's a miracle', it says 'we need to figure out how gravity fits in with quantum physics to investigate further back in time; we currently don't know the answer'.
