The photon doesn't know anything. It does not have a brain.

Excellent. So you agree it is not a hot photon or a cold photon; just a
photon.

Yes, but it is their number and individual frequency i.e energy that
determines whether the body warms or cools.

And blackbody
radiation is not absorbed by atoms.

Curious - what do you think absorbs/interacts with the photon when it
enters the 'body' in question?

Blackbody radiation is continuum radiation which is mainly absorbed by
phonons. Moreover, at terrestrial temperatures electronic absorption, i.e.
line absorption by atoms, is frozen out. That type of absorption and
emission only occurs at near infrared and visible wavelengths.
