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.

“Cold” is only a descriptive term while “heat” is an actual scientific term. On the atomic and subatomic levels, the particles are constantly moving or vibrating and as long as this is happening, there will be heat. If you defined cold as an absence of heat, then cold technically doesn’t exist because absolute zero (where all particles completely stop moving and there is no heat) doesn’t exist in the universe.
