Religion primarily concerns itself with metaphysical questions concerning purpose, morality, and other existential matters. Science is functionally unable to answer these types of things.

Secular philosophy is religions “opposition” when it comes to these things, not science. But of course even many of the philosophers stem their work from a religious foundation.

There are many religious groups that aren’t particularly concerned at all with answering “where does the sun go at night” (I’m of course using that line as a placeholder for any scientific question). They leave those up to science. There aren’t many Buddhist sects that have absolutely no theological concerns whatsoever. No functional or active concepts of afterlife or souls or whatever else. Or at the very least, it isn’t a focus of the sects. It isn’t the point of their religion.
