@spendius,
One of the oldest examples of writing was unearthed in Chaldea by Sir Henry Layard and thought to come from the Palace Library at Ninevah. The specimens have been dated, no doubt accurately, to around 4,000 B.C. They were written on clay tablets with a reed stylus probably similar to the metal ones that the priests, who had a significant hand in making me what I am today, insisted we used for our 3 or 4 hour nightly homework. They would look at nothing written with a ball-point pen. They thought them beneath their dignity as God's representatives on earth. As does the President when he signs an important document. I wonder how many pens used by the signatories of the United States Declaration of Independence are exhibited in museums today. As are relics of the Saints in various roadside attractions designed to catch the eye of a bored motorist.
One of these tablets is in the British Museum. It is an account of the Flood. Experts believe that the Hebrews founded the story of the Flood in the Book of Genesis on this Chaldean narrative written over 2,000 years previously. Obviously the story would get fancied up in the retelling over such a period of time.
It is a very elaborate work and seems unlikely to be the work of somebody having everybody on. Which then, by internal logic, makes a real Flood likely to be a real historical event. Those scoffing at the story are merely displaying their unscholarly fatuousness.
The value of such a story would be in the idea that the Flood was a punishment for behaving as animals do. And thus help persuade people to behave in a proper and decorous manner against all their inclinations. For that to work the people have to believe that the Flood was a punishment just as we are supposedly threatened by the Global Warmers to be going to be punished for our behaviour. "We" being mankind in this case. Not us on here. The pent up fury of the Lord on High takes a while to build up and includes warnings as He stays his hand in His merciful goodness. So an "I'm alright Jack" attitude is perfectly understandable.
Had we continued to behave as animals do, and there seems no particular reason why we shouldn't have done, except for this story, we wouldn't have pubs and high-definition television, lingerie, Slumberland mattresses and all these interesting tasks to accomplish.
That's why I treat these myths and legends with profound respect and grateful thanksgiving. As do all intellectuals above Gamma Plus.
