Moses, Hebrews leaving Egypt, etc. - backed up by other histories?

[Oswald Acted Alone, You Kook]

Let's consult my Biblical Archeology Textbook:

"There are no specific Egyptian references to the sojourn, the Exodus, Joseph, or Moses. For two reasons this silence is not surprising. First, any record of Joseph was lost in the Egyptian purge of Hyksos history. It is not possible to give even a full list of Hyksos kings, let alone their viziers. Second, since the Egyptians had little interest in recording setbacks it is unlikely that the exodus and its attendant problems would have been recorded."

Surprised the "Joseph was Imhotep" theory hasn't been mentioned here.
