Significant Find by the Israel Antiquities Authority

[Confused Ape]

"Moses" would have been a character name based upon the myths of polytheism

Amusingly, the root form "mss" (moses, messes, or mosis) in Egyptian meant "born to" or "son of." Thus, Thutmoses meant "Born to Thoth," Ramesses meant "Born to Ra" and Ahmoses meant "Born to Ah."

"Moses" by itself, in Egyptian, would mean "Born to Fucking Nobody!"

Maybe there's a clue here on Jewish Answers org

Origin of the Name Moses/Moshe

Moses
In Egyptian, Moshe means a son. Thus, his naming is prefaced by a phrase that is literally translated, ‘he became to her as a son’ (cf. Ibn Ezra; Hadar Zekenim). Significantly, the suffix moshe is found (and exclusively so) in the names of many Pharaohs of the 18th Dynasty, such as Ka-moshe (‘son of [Ra’s] majesty’), Ach-moshe (Ahmose; ‘son of the moon,’ or ‘the moon is born’) and Toth-moshe (Thutmose; ‘son of Toth’).

Maybe, when the story first started, he was given a name which translated as 'he became to her as a son'. Later on the name got shortened to Moses which just means 'son'. Then there's the explanation that Pharaoh's daughter named him Moses because she drew him out of the water.

As the story develops, we realize that his sister, too, is not explicitly named, nor is the woman who saved this Hebrew child from the Nile introduced by name; rather, she is referred to simply as "Pharaoh's daughter." The only explicit name given in the story appears in verse 10: "When the child grew up, she brought him to Pharaoh's daughter, who made him her son. She named him Moses, explaining, 'I drew him out of the water.'"

It is highly unlikely that Pharaoh's daughter knew Hebrew, for if so, she would surely have called the child Mashui, using the passive form of the verb 'to draw water', not Moshe (Moses), which is an active form; for the child 'was drawn out' of the water and did not draw out others. Indeed, early commentators (such as Ibn Ezra) as well as modern ones (the Netziv) surmised that Moshe is not a Hebrew word, rather an Egyptian one, and that the Torah found a connection between the sound of the Egyptian word Moshe and the meaning of the Hebrew verb m-sh-h.

So, what we ended up with isn't how it started out.
