Why were there no theaters in Egypt of the Pharaohs

Why were there no theaters in Egypt of the Pharaohs?
My previous post started with the statement that the stage has been part of human civilizations since the dawn of times, with one exception. Since no one reads this, no one asked, and since it was a long drawn out post I didn't want to go into it. The ancient Egyptians had no theaters. It is interesting that all we know about the ancient Egyptians is based on their art on tombs and temples, while at the same time art was never part of the Egyptian culture. The Egyptians never developed the concept of art for art's sake. You might look at something like this and wonder how is this not art? It's not. It's an image of the ram headed god Khnum taking the king by the hand and imparting some life affirming aspect of existence upon him (1. you can tell by the ank between them and 2 I don't really know the specific meaning of the scene), it served a practical and functional purpose which was not artistic. The Egyptians never built a theater, all of their shows and enactments took place at the temple courtyards. There were several ceremonies during the year, at different temples, that would have rivaled any Broadway musical extravaganza, and people attended en masse. But these were not shows and they were not art, they served a function. They would have been as artistic to the population as a catholic mass is to catholics. Egyptians worshiped, told stories and tall tales, documented events and asked for divine intervention on their walls. Here is a war scene on a wall of the Ramesseum depicting the chaos of war; chaos is rare on Egyptian walls.
Art in Egypt always served a purpose and it never had any value or meaning outside of that purpose. For that reason they never developed theater or painting or even sculpture as art forms. Hieroglyphs may be artistic to us, but to the Egyptians they were no more artistic than this text. Well, perhaps a bit more artistic than this text since only 5 or 6 percent of the population were literate and to them the written text would have been stylistic rather than communicative.
And, on an unrelated topic, these were the very last hieroglyphs written. They are in Elephantine Island which was the last hold of Egyptian culture before Constantine had every living thing on the island killed and the language of the hieroglyphs was forgotten.
