There is no archiological or historical evidence that the events depicted in Exodus ever happened.
These central events in the history of the Israelites are not corroborated in documents external to the Bible or in archaeological findings. Most historians today agree that at best, the stay in Egypt and the exodous occurred in a few families and that their private story was expanded and "nationalized" to fit the needs of theological ideology. Many archaeologists, including Israel Finkelstein, Zahi Hawass, Ze'ev Herzog and William G. Dever, regard the Exodus as non-historical, at best containing a small germ of truth.
More than a century of archaeological research has discovered nothing which could support the narrative elements of the book of Exodus - the four centuries sojourn in Egypt, the escape of well over a million Israelites from the Delta, or the three months journey through the wilderness to Sinai. Archaeological research has found no evidence that the Sinai desert ever hosted, or could have hosted, millions of people, nor of a massive population increase in Canaan, estimated to have had a population of between 50,000 and 100,000 at the time.
The Egyptian records themselves have no mention of anything recorded in Exodus, the wilderness of the southern Sinai peninsula shows no traces of a mass-migration such as Exodus describes, and virtually all the place-names mentioned, including Goshen (the area within Egypt where the Israelites supposedly lived), the store-cities of Pithom and Rameses, the site of the crossing of the Red Sea, and even Mt Sinai itself, have resisted identification.
The archaeology of Palestine has equally failed to substantiate the Bible's account of the invasion of Canaan by the Israelites arriving from Egypt some forty years later - of the 31 cities supposedly conquered by Joshua, only one (Bethel) shows a destruction level that equates to the Biblical narrative, and there is general agreement that the origins of Israel lie within Canaan itself. Even those scholars who hold the Exodus to represent historical truth concede that the most the evidence can suggest is plausibility.
Ain't no mention of jews or 10 plagues in this http://www.touregypt.net/ehistory.htm extensive history of Egypt.
Point one of my proof is that all of the events of Exodus are described ONLY in the Bible.

BTW: The Bible never describes the Israelites as "slaves." The Israelites perform forced labor for Pharaoh, and they have Egyptian taskmasters who "ruthlessly imposed" on them. But they don't seem to be slaves in the way Joseph was a slave to Potiphar. The Israelites aren't owned by Egyptians. There appear to be limits on their maltreatment: They are compelled to supply labor, but there's no mention of them being deprived of property or banned from other work. The word "slave," which is thrown about so casually everywhere else in the Bibley doesn't appear in reference to the Israelites .
