There are many ancient myths from many
different cultures over the world concerning a great flood. However,
this does not have to mean that every myth was talking about the same
disaster. In the Mesopotamiam myths; The "gods"
either created or foresaw the coming flood. The Lord Enlil saw this
happening as an opportunity to undo their creation, which they thought
was huge failure because of the corruption and lawlessnes of the people
which started with the interference of the "fallen angels" and the
birth of the giants.
The god Enki (Ea), regarded as a co-creator and protector of mankind, didn't want to destroy his creation so, despite the agreement of the gods to let mankind perish, he told a pius man known as Ziusudra (Sumerian), Utna-pishtim (Old Babylonian), and Noah (both Babylonian and Hebrew "Book of Genesis") about the coming flood and instructed him to build a giant wooden ark to save him and his family.
Quoting from Wikipedia:
to Sumerian mythology, Enki also assisted humanity to survive the
Deluge designed to kill them. In the Legend of Atrahasis, Enlil, the
king of the gods, sets out to eliminate humanity, the noise of whose
mating is offensive to his ears.
He successively sends drought, famine and plague to eliminate humanity, but Enki thwarts his half-brother's plans by teaching Atrahasis about irrigation, granaries and medicine. Humans again proliferate a fourth time. Enraged, Enlil convenes a Council of Deities and gets them to promise not to tell humankind that he plans their total annihilation.
Enki does not tell Atrahasis, but instead tells the walls of Atrahasis' (a.k.a. Utnapishtim, Ziusudra, Noah) reed hut of Enlil's plan, thus covertly rescuing Atrahasis by either instructing him to build some kind of a boat for his family, or by bringing him into the heavens in a magic boat.
After the seven day Deluge, the flood hero frees a swallow, a raven and a dove in an effort to find if the flood waters have receded. On the boat landing, a sacrifice is organised to the gods. Enlil is angry his will has been thwarted yet again, and Enki is named as the culprit. As the god of what we would call ecology, Enki explains that Enlil is unfair to punish the guiltless Atrahasis for the sins of his fellows, and secures a promise that the gods will not eliminate humankind if they practice birth control and live within the means of the natural world.
The threat is made, however, that if humans do not honor their side of the coventant the gods will be free to wreak havoc once again. This is apparently the oldest of the surviving Middle Eastern Deluge myths."
Instead of Enki, in the first book of Enoch it was the arch-angel Uriel who warned Noah of the Deluge and instructed him to build the ark. Could it be that they were the same being, as Enki became the arch-angel Uriel in his further evolution?
According to Edgar Cayce, the biblical "Deluge" would have happened around 22,006 BC. Because of the catastrophy, the Atlantean land land broke up into three large and two smaller islands. It is not to be confused with the final demise of Atlantis which happened around 9,900 BC, when the last remaining island of Atlantis (which Plato actually spoke of) finally disappeared into the Atlantic Ocean. (More in the chapter about Atlantis: The Three Catastrophes.)
Like in the Bible, the final flood of Atlantis had been similairly described as a punishment from Zeus; the god of the gods, in Plato's dialogue "Critias".
The book: "A Dweller on two Planets" by Phylos the Thibetan and claimed to be channeled through Frederick S. Oliver, described various previous lives of a soul called Phylos, including one where he lived in Atlantis, and he also described some insights from the "Book of Life", which is also known as the "Akashic Records" in New Age terminology. At page 404 of this book, the author wrote that he saw in the Book of Life that the vessel of "Nepth" (appearently Noah), was carried by the great flood from Atlantis into Africa, from where it at finally came to a halt in Asia. (The book "A Dweller on two Planets" is fully readable online at: www.sacred-texts.com.)
Noah's story also bears some similarities with both the Chinese "Fu Xi" (or "Fohi"), who was the very first ruler of China according to Chinese mythology, and "Manu"; known in various Hindu traditions as the progenitor of mankind and the very first king to rule this earth.
