[Quranic Reflection]: The Aten.

[Paleophyte]

So there are two theories now: either Joseph was "Imhotep", or Joseph was "Akhnaten".

These aren't theories. They aren't even informed guesses.

Akhenaten was the younger son of Pharaoh Amenhotep III and his wife Tiye. He was about as Jewish as a bacon cheese burger. Any attempt to tie him to Joseph is laughably stoopid.

Little is known about Imhotep, with only a few inscriptions that mention him during his life. So your attempt to connect him to Joseph is nothing more than fanciful hand-waving.

Joseph is a fictional character created in Babylon as part of the pretext for repatriating the Jews to Israel following the First Diaspora. His role in the narrative is both to explain what the Jews were doing in Egypt to begin with (fled to Egypt after the Babylonians kicked our asses didn't fit the narrative) and to justify rule by the House of Joseph over the other Jewish tribes. He's a nasty little bit of Early Iron Age jingo and politics. First cousin to Paul Bunyan and older brother of the Cheshire Cat.
