I watched it all. Every episode is like what you described, just in a different location, and probably serving as a root to some myth.

Like Plato making up the story of Atlantis, based on what happened to Helike.

Its very obvious in today's world, how such a thing could be, and is much more believable than the nonsense of "Atlantis".

Also learnt about Sargon of Akkad, so that was interesting.
