Some here are pointing out that at one time the Mediterranean sea dried out completely, but that was millions of years before the making of these axes. Also, sea levels were much lower during the various cice age glaciations. How much lower? Unknown. Enough to form a land bridge from Turkey, Greece or Egypt to Crete? No, the seas around Crete are too deep.
Therefore, they have to assume the makers of the hand axes had some form of water transportation. Boats? Rafts?
I think I can dig that, thanx
