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.

Imagine you have a box of crayons. One of the crayons is super bright and colorful, like a shiny gold crayon. The other crayon is plain and doesn’t have any color, like a clear crayon.

Now, when you color with the gold crayon, you’re adding lots of bright color to the paper. This is like when something is hot; it has a lot of energy.

But when you color with the clear crayon, you’re not really adding any color. It’s not that you’re adding “no-color” to the paper; you’re just not adding any color at all. This is like when something is cold; it doesn’t have much energy.

So, when we say “cold is the absence of heat,” it’s like saying the clear crayon is the absence of color. It’s not that “cold” is a thing by itself; it’s just what we feel when there’s not much heat or energy around.

And just like the countryside isn’t the “absence of a city” but a different kind of place, “cold” is a different kind of feeling we get when there’s less heat. But in science terms, we think of cold as having less energy compared to something hot.
