It takes a guy forty years to "lead" Isrealites to a destination that is a three week journey away.
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.
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.
Why is there no documentation of this anywhere other than the bible?
