There are questions, and then there are meta-questions. For example, “can god create a boulder so heavy that he can’t lift it?” is a question. The meta-question might be “is this question well-formed?” or “is this question answerable?” I suggest that your question about what preceded the big bang is fundamentally unanswerable. If you can’t argue from logic (and you can’t, for proto-origins), then you have to argue from evidence. But the only evidence we have is from a universe which didn’t exist before the big bang. For me, the answer to “where did all this come from” is “we can’t know.” Not “we don’t know”, or “we don’t know yet”, or even “we’ll never know”. We can’t know. It might not be a satisfying answer, but it is a useful answer, if for no other reason than it removes one question from the list I’d like answered before I die.
