Well and truly absurd humans are space orcs proposal - human and earth life in general are some of the only beings in the universe that can't perceive math. Every other race doesn't have math or numbers because that would be like if we had to invent an unbelievable complicated system to describe the state of experiencing visible light or sound. Everyone everywhere except humans has got a "math organ" and numbers are tangible physical things that can be measured, except measurements are completely foreign to everyone because those are described by numbers which are simply a sense we lack and had to create for ourselves.
Every other race thinks of us as similar to highly intelligent, blind cave salamanders who have learned to develop a horrific party trick where they turn the sense of sight into a nuclear bomb.
