When it’s “freezing cold” or “ice cold” outside, what do you think is freezing? When something is “boiling hot”, what is boiling exactly?
We use water to describe temperature even without using Celsius, because it’s everywhere around us, and we are literally made of this stuff. It’s also one of the only materials that goes through three different states in our usual temperature range, so using those as a reference point to measure temperature makes perfect sense imo.
