I'll give you the actual answer:
Megafauna

Each and every single time (to this day), whenever one tries to make agriculture,they get raided by herds of elephants, hippos, wildebeasts, zebras, etcs

>hurr durr Egypt did it
Yeah, they did, by killing every Hippo.
Every single civilization that managed to rise in the Nile has a culture that promotes the killing of Megafauna precisely because they are threats to the farmlands.

They were pretty helpless until guns and barbed wires arrived
Be glad that Africa never learned to farm. Lest it would have led to the extinction of Elephants
