Witch area of the civilization was upper Egypt

Here is three possible explanations:

Upper Egypt is between the Cataracts of the Nile above modern-day Aswan, downriver (northwards) to the area of El-Ayait, which places modern-day Cairo in Lower Egypt. The northern (downriver) part of Upper Egypt, between Sohag and El-Ayait, is also known as Middle Egypt.

Ancient Egypt was divided into two regions, namely Upper Egypt and Lower Egypt. To the north was Lower Egypt, where the Nile stretched out with its several branches to form the Nile Delta. To the south was Upper Egypt, stretching to Aswan.

Upper Egypt, Arabic Qiblī Miṣr, also called Al-Ṣaʿīd (“The Upland”), geographic and cultural division of Egypt, generally consisting of the Nile River valley south of the delta and the 30th parallel N. It consists of the entire Nile River valley from Cairo south to Lake Nasser (formed by the Aswan High Dam).
