Counterpoint: I own a fairly recent book that contains the specifications of the Starship Enterprise (with probably more detail that those on that tablet).
"It doesn't really matter." The Starship Enterprise "is a thing of itself and it has a vitality forever."
The fact that the story of the great flood existed before the biblical account is evidence in favor of the story, not a refutation. Every person of faith knows the true source of the story, it is not a Babylonian invention. Many early cultures, I would venture ALL of them, had the same story. This guy is just an outsider and not informed.
Given what I understand to be the preeminent position Babylon held in the ancient world, it seems plausible that the Biblical flood story was influenced by the Babylonian one, although both may still have had a common antecedent. This is not necessarily supporting evidence placing one particular version of the narrative over another.
You will find flood stories from around the world, from peoples with no contact with each other. You're looking at some combination of common unconsciousness or events at the end of the last ice age.
