It was a localised flood caused by the receding glaciers of the last ice-age. The earth wasn't destroyed at all.
Lake Agassiz was a vast glacial lake on northen canada, holding about one and half times the water, all the rivers in the world carry to the seas, in an entire year. About 8,200 years ago the lake broke and all the water emptied into the atlantic in a few hours time. This caused Britain to become an island. https://en.wikipedia.org/wiki/Lake_Agassiz https://en.wikipedia.org/wiki/Lake_Agassiz --- <jr_esq@...> wrote : Asteroids could definitely destroy human civilizations or set it back to the time of the Dark Ages. It's also nature's way of saying to start a new way of living. This has happened in the recorded past of humanity, such as the time when the earth was destroyed by water during Noah's time. This could be one of the important reasons for humans to explore and colonize the Moon and Mars. Humans on these new worlds could help preserve the knowledge throughout history in case the civilizations on earth are destroyed.

A relatively small lump of rock – a small asteroid, perhaps only a few hundred metres across – plunging to Earth would devastate a continent or trigger tsunamis. Civilisation would be set back several centuries. It is a real risk, say a group of astronauts and astronomers who are to highlight the threat facing humanity by marking 30 June as Asteroid Day. The chosen date marks the anniversary of the “Tunguska event”, when a small asteroid or comet exploded above Siberia with the force of 1,000 atomic bombs. The largest impact event on Earth in recorded history, it occurred on 30 June 1908.
