Eli5 is there no such thing as cold?

My SO said the above statement and gave me an explanation “Cold is the absence of heat or energy”, it does make sense however in my head it is like saying (in very simplistic terms) “the countryside is the absence of a city” and that is just a ridiculous statement.

It’s like how darkness is the absence of light.

Light is a thing that exists both physically (we can interact with it and make lasers) and conceptually (we can unambiguously imagine something being well-lit).

Darkness is not a thing that exists physically (by definition it has nothing to interact with, and we can’t make “anti-lasers”), but it exists conceptually (we can unambiguously imagine something being not well-lit).
