HOW ABOUT THIS?
In fact, the quest for Biblical accounts of ancient Egypt at least into the 19th Dynasty of Egypt's New Kingdom, take on an interesting approach by most investigators.
Essentially, since there is no evidence to clearly support the existence of Joseph, or Moses, or the Israeli Exodus, most of the investigation examines what was possible, what cannot be ruled out, or what fits into and Egyptian context. In other words, is it possible that such events or people could have existed from what we know of ancient Egypt.
Some specifics are very possible, such as Joseph's rise to importance in the Egyptian court. Other events, such as the Exodus, as specifically told in the Bible, are much more difficult.
Though the Egyptians may not have liked to record defeats, it would seem very probable that, were the disasters inflicted upon them as detailed in the Bible, there would have survived some textual evidence. For example, the Egyptians certainly recorded events such as eclipses of the sun and the levels of the Nile Flood.
Were the Nile to have turned to blood and every firstborn child suddenly have died, not to mention all of the other plagues mentioned in Exodus, there would have doubtless been some record left, particularly during the New Kingdom. Tomb records frequently provide us with the most meager of details, and we have, from that period, many thousands of documents recording civil actions and even commercial contracts.
"Despite the mass of contemporary records that have been unearthed in Egypt, not one historical reference to the presence of the Israelites has yet been found there. Not a single mention of Joseph, the Pharaoh's 'Grand Vizier'. Not a word about Moses, or the spectacular flight from Egypt and the destruction of the pursuing Egyptian army."
Magnus Magnusson (The Archaeology of the Bible Lands - BC, p43)
Also... for many centuries the Egyptians were present in Palestine, controlling the trade routes and importing the timber, olive oil and minerals not found in Egypt.
Archaeology has uncovered dramatic evidence of this pervasive Egyptian presence in 'Canaan'– yet nowhere does the Bible refer to Egyptians outside of Egypt. It would spoil the story!!
How could Hebrews escape into the promised land if the Bible admitted Egyptians were running the show there too?
'Neither Moses, nor an enslaved Israel nor the event of this Exodus are recorded in any known ancient records outside the Bible.
Although its climate has preserved the tiniest traces of ancient bedouin encampments and the sparse 5000-year-old villages of mine workers there is not a single trace of Moses or the Israelites.'
