ArrayFinkelstein and Silberman point out that there is still no evidence for the existence of Abraham, Isaac, Jacob, Lot, Moses, and Joshua. There is no evidence that Jewish people existed as an identified people that were enslaved in Egypt. There is no evidence that over 600,000 men (plus women and children - the number could have been over a million) had an exodus from Egypt and wandered in the desert for 40 years. According to the Bible, 38 of these 40 years were actually spent encamped at Kadesh-barnea. This area has been turned upside down for decades, looking for even a tiny piece of pottery from this supposed time. It is not likely that this many people would have lived here this long and not left archeological evidence[/quote]
