When did black and white people first learn of each others existence?

i was thinking about pharaohs when writing this (incest breeders), but you are right about "normal" egyptians mixing

Fucking lmao

Hittites were from Anatolia and the Levant. Ask any American and they'll tell you that those places are in the Middle East. No matter how accurate or inaccurate that may be, that's how most people feel. The people of that region aren't much different from Arabs. I purposely didn't use the word Arab because I knew you were gonna try this. Most people wouldn't consider anyone with ancestry outside of Europe to be white.

>Nubian cavalry
No such thing, they used Numidians who are Amazigh and not amanig

>since the idea of race based on skin color is a relatively new concept that Americans created
Race based on skin colour barely actually ever existed as a concept, race based on physical characteristics is indeed much older
