Hello there!
Back in the days of the early Egyptians, they did not know about "north" or "south." Due to this, they did not think to orient their kingdom in the way we do now. They took the Nile River, which flows from south to north as their reference. Therefore, the southern part was known as "Upper Egypt" while the northern region was called "Lower Egypt."
I hope this helps!
