Odds are I'll get downvoted for this. Did calculus Exist in 3 B.C.? Did the Earth orbit around the Sun in 2800 B.C.? Did dinosaurs exist way, way back in the day? My point being, does discovering something suddenly mean it exists? Perhaps things do not suddenly exist, perhaps they are discovered. Math has always existed. It still exists to this day. Math is discovered. The rules don't change. PTSD exists. It existed…
> Math has always existed.
I would say that laws of the Universe that math describes always existed but not math. Math is more of a language to describe something, and you can't say that the word "apple" always existed and was only discovered later. Apples existed long before the word got invented to describe it, though.
