I believe Moses was real. Some calculations indicate that he was 80 years old at the beginning of Exodus, which means he didn't wander in the desert for 40 years.
Many are beginning to recognize an error in the translation of the number 40. It should mean 'many.' Notice how reaccuring the number 40 is in biblical writings?
Most of the Jews that left Egypt during the Exodus died inroute.
I also believe Mount Siani(sp) is in Saudia Arabia.
I've heard similar things in regards to "12".
