Isn't Buddhism a philosophy, not a religion?
In Asia Buddhism has always been a religion: temples, monks, merit, gods, rebirth and worship of relics. The philosophy-only version is a modern Western form.
The Pali discourses speak of gods, heavens and hells, rebirth, and the Buddha's relics. Buddhists across Asia make offerings, chant and go for refuge. The idea of Buddhism as a purely rational philosophy grew up in the nineteenth and twentieth centuries, partly in conversation with Western science.
Either way, Buddhism makes claims about ultimate reality: that there is no Creator, no self, and that the way out is extinguishment. Those claims can be tested, and the Bible disagrees with them.
I take refuge in the Buddha, I take refuge in the Teaching, I take refuge in the Saṅgha.

“Well then, brahmin, you yourself should fairly divide the Buddha’s relics in eight portions.”
