That is the presumption others are calling you out for. Things very clearly act appear to act with purpose, they just clearly don't provide it for themselves. You are presuming one solution to the problem (that appearance does not hold in reality), but there is another one.

A storm can appear to act with purpose too, or a planet orbiting a star, yet I doubt you assign it agency. It's fundamentally your choice to assign something agency or not, whether you are right or wrong to do so, is not an empirical question. It is a teleological one. "Call me out" all you want, this is very basic.
