The TLDR; no mentions of Moses in Egyptian or Persian texts until about the 4th century BCE. He may have been a Hebrew specific quasi mythic figure based on a possible real person. But there’s no evidence at all.
Which makes sense, because that’s the timeframe that the Achaemenid Empire conquered Babylon and started letting the exiles return to Judah. Exiles who compiled a new Torah from scraps they saved and from making shit up.
Made up, for a given value of made up. They weren’t completely inventing things whole cloth, and had some surviving material to work off of. That and Babylonian records. They had those too. Since Babylon was gone… Well, finders keepers.
