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.

Your example is not really good because the countryside is a real thing. It’s a category of real things like farmland, forest, swamp, etc.

There isn’t something physical that is called cold, it’s just how to name the absence of heat. Same as shadow isn’t a real tangible things, it’s just the absence of light.
