Kind of is my answer. I would even back up and say the Big Bang model of the universe describes what we see in reality quite well, especially in regards to the distribution of elements, the redshift of light, the distribution and wide-scale structure of galaxies, the cosmic microwave background, etc.
So all of these provide confidence that yes indeed our universe came from a very hot and dense initial state. However, the mathematical framework that allows for such confidence in this model, i.e. General Relativity, breaks down and fails to describe what happens in such cases (i.e. a singularity or singularity-like state). Generally speaking, physicists hate infinities and that is all we get at the beginning of the universe, indicating that there is something more to the picture. Hence the search for quantum gravity… This a-capella science video sums up the challenge pretty nicely:
It’s a pretty deep video actually that makes more sense the more you learn about these topics and it even describes attempts at string theory to understand our universe and many of the problems that we face.
The BVG theorem gets way too much attention in apologetics arguments. We have several who use a version of the Kalam argument (like WLC or Hugh Ross with Reasons to Believe) who hold the Theorem over the heads of practicing cosmologists essentially implying that they know how to really apply this Theorem as absolute proof that God created the universe.
I was curious myself (not being a cosmologist) as to how people who professionally work in the field think of such a theorem. So one way to do this is search Google Scholar or something equivalent on who has cited the BVG theorem paper. I see some 300+ citations in my search. One thing I definitely see is that it isn’t hailed as a grand apologetic that the only model of the universe is in fact the one where we have no explanation except god. But yet, that is how it is used by Christian apologists and then the rest of us might as well take their word for it because they definitely are quite confident.
At the end of the day though, I don’t know. For all I know we will never find any explanations for the beginning of our universe (maybe not in our lifetime or ever) and maybe this really is finally clear evidence of God that since science can’t explain something, God really did something in the natural world (without saying how or what he did or how he actually interacts with physical matter). Can someone believe by faith that God made the universe, yes of course! But that is a big difference from holding science over scientists heads and saying “we know how to really understand your theorems” and claiming it as absolute proof of God.
