Google “Sinai inscriptions”, and then select “images” from the menu. You’ll see the graffiti left by Hebrew slaves in the Sinai mines, and at least one of them mentions Moses.
As well, the book “The World’s Oldest Alphabet”, by Petrovich, goes into those inscriptions in much greater detail (a hard read, for scholars, but the info is there).
