So materialism - the world view which says that only things that are physical are real - is rejected by you because it's philosophical?! It's really just a statement that follows from science being the main (perhaps only) meaningful way to talk about the world.
Which is what you are saying.
How can you stay consistent and reject materialism, yet be an atheist who thinks of science as you do?
What this has really been, is a wild goose chase to deny being a materialist or that the universe is a brute fact so you can ignore my original question.
Note, you haven't even explained how physics could in principle answer the question why the universe exists. You've simply replied with assertions.
