On this date in 2105 BCE (1656 from Creation), Noah and family entered the Ark. It wasn't until seven days later, however, that the intense rains began for 40 days and 40 nights. The delay was to allow a proper mourning period for Methuselah, the righteous grandfather of Noah who had just died at the age of 969 years, history's oldest human being. Noah and his family (and the animals) would remain on the Ark for over a year, until the flood waters had sufficiently subsided.
