From here:
Another argument that the Exodus never occurred is that there are no signs that the Israelites wandered in the Sinai desert for 40 years. However, we must remember that during the Exodus the Israelites were forced to live nomadic lives. No longer did they reside in villages with sturdy houses and artifacts that could have survived as evidence. Instead, in the wilderness environment, every item had to be used to its fullest capacity and then, if possible, recycled. Also, the portable tent encampments during those 40 years would have left few or no traces that could be found 3, 400 years later, especially in the shifting desert sands.
Interestingly, recent satellite infrared technology has revealed ancient caravan routes in the Sinai. George Stephen, a satellite-image analyst, discovered evidence in the satellite photographs of ancient tracks made by “a massive number of people” going “from the Nile Delta straight south along the east bank of the Gulf of Suez and around the tip of the Sinai Peninsula.” He also saw huge campsites along the route, one that fits the description given in the book of Exodus (Price 1997:137).
Could this evidence be a coincidence? If nothing else at least it shows that a large number of people could be sustained in the same region and on the same path as that taken by the Israelites during the Exodus.
