Noah, at 600 years of age, his wife, his sons and their wives entered the ark under God’s instructions 7 days before the start of the rain. Pairs of all animals and birds also entered the ark. When the heavy rain started it lasted for 40 days and the resultant flood lasted for 5 months with even the mountains being submerged under 20 feet of water. All human beings, animals, birds and living creatures were exterminated by this flood except those in the floating ark.
