They showed this program again tonight. It was on the History Channel (so I may have been wrong last time when I said Discovery Channel, unless it played on both). The skeptical scientist was actually more open minded. He has a Ph.D. in geology and has made some non-traditional assessments such as the Sphinx being dated at 5000 B.C. It really was fairly even handed, with neither side being able to conclusively prove their case, until the very end when the submerged head was found.
