The Nile floods every year, and there will be floods, which will bring the necessary farming conditions to Egypt-fertile soil ~
But as you said, there is no myth story of flood in Egyptian mythology at present ~
What you said is probably the story of Noah's ark flooding mentioned in the Bible ~
However, it is worth noting that the myth of prehistoric floods can be found in many parts of the world, including China and Maya, so if it is a global flood, it must have been recorded in Egypt, but it has not been discovered so far ~
However, if you know Atlantis, you may know that ancient Egypt and Atlantis have some origins. According to the dialogue written by Bertrand, Egypt was within the sphere of influence of Atlantis at that time, and Atlantis was destroyed by a flood, so it was speculated that the Egyptians were descendants of Atlantis. With regard to records, you can get to know the situation with EdgarCayse in the record hall, which are all related. If there is, Egypt's flood records are probably buried in the record hall. It is said that Thoth, the god of wisdom in Egypt, is a survivor of the Atlantis disaster. It is also said that there is a book called Thoth that records the flood.
