The myth of Noah’s Flood is not a Jewish matter, it is pretty well universal. The Biblical tale of the flood is uninspired because it is borrowed from much earlier Middle Eastern literature including the oldest known narrative writings in Sumeria in southern Mesopotamia.
It is a mistake to think that it is based on a reality and go searching for scientific corroboration, as Caleb points out; this is without point. (Of course this does not stop the crack-pots from trying). The Genesis flood is so hopelessly flawed as a literal account as to immediately dismiss its truthfulness. One small family could not save the world’s fauna in a floating chest and then have all the animals subsequently journey back to their place of origin after the water dried up. These are just the first two of a hundred arguments defying a literal interpretation. As for the Garden of Eden, come on! This reads like a myth and waddles like a myth and quacks like a myth.
It is also a mistake to think that myths are true in essence or existed as a kernel of truth but were elaborated for the sake of the literary effect. This is not how myth functions. It is this gross assumption which gets writers to make fatuous and startling headline claims like the ones in the title of this thread; proof of The Flood or finding the Garden of Eden. No! Myth is usually a universal tale, part of a coherent broader pattern of stories, which explains the unexplainable or reconciles the irreconcilable. It makes only for a story not a fact of history or science.
