Another case in point is the biblical record of the exodus of the Israelites from Egypt and their subsequent 40-year wandering in the Sinai wilderness. According to census figures in the book of Numbers, the Israelite population would have been between 2.5 to 3 million people, all of whom died in the wilderness for their disobedience, yet extensive archaeological work by Israeli archaeologist Eliezer Oren over a period of 10 years
"failed to provide a single shred of evidence that the biblical account of the Exodus from Egypt ever happened"
(Barry Brown, "Israeli Archaeologist Reports No Evidence to Back Exodus Story," News Toronto Bureau, Feb. 27, 1988).
Oren reported that although he found papyrus notes that reported the sighting of two runaway slaves, no records were found that mentioned a horde of millions: "They (papyrus notes) were spotted and the biblical account of 2.5 million people with 600,000 of military age weren't?" Oren asked in a speech at the Royal Ontario Museum. That is certainly a legitimate question. Up to 3 million Israelites camped in a wilderness for 40 years, but no traces of their camps, burials, and millions of animal sacrifices could be found in ten years of excavations.
