Vlud,
Firstly philosophical materialism is only as good as long as there is material as is methodological materialism.
Insofar as I can unscramble that sentence into a comprehensible thought, it's axiomatic that materialism deals with the material. You and I can speculate as much as we like about the supposed non-material - gods, leprechauns, whatever - but materialism could never have anything to say about how real any of those speculations might be.
The problem though - your problem in fact - is that
neither can anything else. And as we both know that I've chased you all over this mb asking you finally to produce a method
of any sort to validate your personal claims of the non-material only for you endlessly to avoid answering, you're stuck with your problem until you finally at least attempt to address it.
No-one else has ever managed it by the way, so good luck with it!
Secondly you are suppressing the very question which exposes you to this.
No doubt you'll be along any time now then to tell us what this "question" is that I'm apparently "suppressing".
I see by the way the you've avoided again answering your difficulty about framing a question that's meaningful. If you take an entirely parochial, Paley's watch level approach to the "the universe" - "it's made of stuff, stuff comes from somewhere, therefore it must have had an origin" etc - then the "what's the origin of the universe then?" - question makes a kind of limited sense, even when you use it as a precursor to yet another argument from personal incredulity.
The problem though is that the universe actually appears to be a lot more complex and nuanced than that. When time itself is likely to be a property of the universe, questions about what happened "before" time just break down. Maybe the universe - or lots of universes - are eternally old; maybe there was a true "nothing" and a quantum borrowing event occurred; maybe, maybe, maybe...
The thing is though, people are working on these questions as we speak using the only tools available that have been shown verifiably to work - the tools of science. That some oaf says, "ah, but science hasn't got all the answers yet so it must be a piece of iron-age folkloric myth wot did it" is so preposterously ludicrous that I wonder that you bother with it, but there it is nonetheless.
