History is recorded, that's the definition of the word. Prehistory is not recorded which is what the 500 kya to 10 kya refers to.

The wikipedia for "Recorded history"[1] draws the distinction this way:

- Before writing: prehistory

- After writing: recorded history

- Both together: human history[2]
