Video was very interesting. I wonder if any of those "axle" assemblies have been brought up, to prove the age and origin of the axle assemblies?
avigate dby cargo boats for millennia
It may be far fetched, but the Suez canal has been used for many years, and the Red Sea has been navigated by cargo boats for millennia..and they could be of a later origin.
looks very promising however, so I hope they process it scientifically, proving their origin and date.
