Which religion claims nothing supernatural at all happened?
Secular versions of Buddhism, versions of neo-paganism that interpret themselves to ultimately be manipulating psychological processes, religions whose conception of the divine is derived from scientific ideas, etc. More generally, many religions that define themselves primarily through practice rather than belief can be compatible with a lack of the supernatural (though of course aren’t necessarily).
