No scientist can deny methodological naturalism, but metaphysical naturalism is optional.
That's not how it works; the metaphysics is irrelevant.
Who do you think you're kidding? The Evolutionary worldview is constantly preached as the fundamental nature of reality as illuminated to us by "science", from the evolution of the cosmos itself, to the human mind. This metaphysical worldview permeates virtually every popular-science publication in the world. If you deny this, you may as well start arguing that the sky isn't blue.
*If* we can find a natural explanation for the phenomena we observe, that is testable, has explanatory power (e.g. gives insight into & understanding of the phenomena), makes successful predictions, links or unifies disparate areas of knowledge, is conceptually and ontologically parsimonious, broadly coheres with our existing body of knowledge, and doesn't raise unanswerable questions - then we simply don't need supernatural or paranormal 'explanations' that typically have none of the features of a good explanation (as above).
Demonstrably false. There is never any *if* ...
If there is no known natural explanation, then all it means is "science" is still working on finding it.
Even prior to the supposed "Big Bang" is now assumed to be a point in time where natural processes simply worked different than they do today. There is never any proposed limit to nature. It is an endless chain of propositions that are followed into the foundations of reality.
Francis Bacon referred to this as the search for the "secret motions" behind all things. It is that assumption of the almighty natural process that underlies all of reality.
That is the root of your mystical naturalist ideology that you've convinced yourself is a science.
So if we have a good explanation, i.e. an explanation that works (like the ToE), it makes no difference whether you believe the universe was created last Thursday complete with a fake history, or any other fanciful mythology or theological conceit, the theory still explains the observations.
it only "works" for you because it aligns with your ideology. See, you still believe that Evolution was arrived at scientifically.
Look at Abiogenesis... it is advanced with basically the same confidence as the ToE, despite its lack of an explanation that "works" ... Failing an explanation that "works", it is simply assumed that "science" is still working on finding the natural-cause explanation.
Your claim that science hinges on a "good explanation" is demonstrably false. The facts show that an underlying Evolutionary (natuarlistic) ideology is always rooted underneath different attempts at modeling an explanation.
It's always been that way. Charles Darwin's grandfather published romantic epics on the story of evolution of all animal life, before Charles was even born. The ideology has always driven everything.
Science makes no claims to truth, it's pragmatic; it says that the current theory is the best available explanation by the pragmatic criteria above, so whatever the underlying nature of reality, it behaves as if the theory is a good model of it.
Always amusing when evolutionists anthropomorphize "Science"
Everything you've wrote in this post is basically just tired, easily refuted propaganda to make your ideology seem more reasonable... make it seem like practitioners of Evolutionary ideology are all objective, skeptical people that are only following the data to the most likely conclusion. This is a laughably false and distorted view of reality.
Let's look at an example of "science" going on right now:
All the mainstream "health experts" encouraging severe lockdowns on states right now, clutching their pearls that any social gathering is going to kill grandma with COVID, that it's worth destroying national economies, and all sorts of other cruel restrictions... Then all of the same "experts" simultaneously looking the other way, or even cheering on mass city gatherings in which they are in political agreement. We can all see the hypocrisy with our own eyes. It's not even hidden anymore. I'd love to see someone try and deny this is happening. Let the liars identify themselves.
