There have been archaeological finds substantiating the Exodus. But like the good doctor says, ancient Egyptians were like modern day Russians which never ever admitted to mistakes or embarrassing outcomes - and what could be more embarrassing than to have your entire nation turned upside down and ruined by the God of your multiplied-million slaves just before those slaves made a hasty exit, followed by an impulsive pursuit to reclaim them as your slaves only to have you and your army swept over and buried in a watery grave.
I think most of the arch evidence you mention first has been debunked or called into question, I'm aware that a much smaller enclave has been substantiated, but the "chariots at the bottom of the Red Sea" thing got tossed a while back I think.
Anyway, I agree that the Egyptians would have sought to erase them in a literal Exodus scenario, but then archaeologists have means to detect that kind of thing too. Anyway, if you seek a literal Exodus I guess you will find one, but I suggest that if you go seeking without any premises you will find a different kind of Exodus, "God of the Vowel People" will be relevant there.
Bc we are also taught that "Hebrew has no vowels," right? Which is a lie, YHWH (a bad transliteration, as it turns out)
are their vowels, you might even google "Hebrew has no vowels" or any of the other phrases in here and...test the theory, if you like. If you find any holes let me know if you would, ty
that isn't the direction I meant to go here, but I'll leave it for now
