The orthodox view deems that prior to ‘unification,’ Upper and Lower Egypt (the ‘two lands’) were two separate kingdoms each with their own regalia. Upper Egypt (south) adopted the white crown, Lower Egypt (north) the Red crown. However, recent finds of an image of the red crown in Upper Egypt (the south, where it shouldn’t be!) generations before unification has called this into question. This leading to an ad hoc explanation as to why.

“It is thus possible that the Red Crown indicated a different aspect of royalty than the White Crown and did not, at that time, have any geographical meaning at all.”

I maintain scholars have shamefully misunderstood the meaning of ‘Upper and Lower Egypt,’ the ‘Two Lands.’ My explanation is so simple it beggars belief – there were indeed were two Egypt’s – one ‘up’ and one ‘down.’ Upper and Lower Egypt were the firmament of heaven (Up) and a fixed flat earth (Lower). Unification, the very foundation upon which Egypt was built is a planetary body, in the guise of Egypt numerous pharaohs (GKS), appearing to traverse (from an earthly POV) between the two lands of heaven and Earth. This is why the regalia of the two lands (crowns, etc.) remained for the whole epoch of Pharaonic Egypt (See The Egyptian Dualism).
