A good example of how science can be made to lie :-)
The documentary is pure conjecture. See a learned bitterly anti-Islam evangelist, David Wood, harshly criticizing Islam but decisively accepting Mecca and refuting the Petra myth.

Also notice the objective of making this documentary described in the commentary under the video: "If true this could shake Islam to it’s roots, because every Muslim is required to pray towards the ‘forbidden gathering place’."
MASJID AL-HARAAM means 'forbidden gathering place' or the SACRED MASJID?
Did Prophet Muhammad (S) start delivering his Message in 621 CE? No, it was 610.
The documentary has been rejected as false even by the most ardent enemies of Islam.
Recall numerous Christian scholars denying the very existence of Jesus Christ!
Much more can be said on the topic but these few lines should be sufficient.
