Glad that these digs are allowed in Saudi Arabia.
I do know that following Sept. 11, the Saudis clamped down on such investigations, especially regarding the 400s-700s AD, as the archeological record therein is not flattering to Mohammad, demonstrating climate collapse, isolation, and warfare during the 500-700s as coincidental to the rise of Islam.
Mohammad’s rise coincided with severe social, economic and political unrest in the peninsula and the Levant.
The Saudis are very busy building over all potential history around the Kaaba, in Mecca.
Because they know there is NO HISTORY of ISLAM or Mohammad in Mecca.
The only thing archeologists would find is the remnants of nomadic PAGAN rituals.
