From my understanding, The Exodus, The Flood etc, Biblical archaeologists can't seem to find any evidence or at least, in not in the areas as described in the Bible and it's good to see Western scholarship being applied to Islam as well. Dan Gibson seems to be one of the few and with this documentary, makes a very strong case presenting the evidence in a very well-paced well researched documentary. It would be good to see to see further research on as to why the Qiblas of the early mosques Dan Gibson presented seem to point to Petra rather than Mecca. I've seen arguments that suggest Gibson got his calculations wrong or early Muslims got their calculations wrong. If Gibson got his calculations wrong then this can be very easily verified by other scholars. But if early Muslims got their calculations wrong, let's examine that further. But at the same time, it would also be good to expand on the early Muslim power struggle and the suggestion the black stone of the Kaaba was moved from Petra to Mecca for safe keeping.
