In what year was the great flood in the bible when it rained for 40 days and 40 nights?

A:In The Bible it rained for forty days and forty nights because God wanted to destroy everyone and every living thing, except Noah and his family and the creatures they took onto the Ark. It rained for this number of days because the number 40, and sometimes other multiples of 20, was commonly used in the Bible, being easy to remember when retelling a story orally.
