Read Genesis chapters 7 and 8
God became displeased with the increasing wickedness of man and determined to destroy mankind with a great flood. According to Genesis chapter 7 and 8, only Noah and his family were saved from the flood by entering a great 450 foot long boat called an “ark” that God had them construct. The book of Genesis tells us that God sent great rains on the earth for 40 days and 40 nights and that the springs of the earth opened up to cover the whole land with a flood of water. This ark floated on the water for some 150 days before coming back to rest upon the land.
Where did the Ark come to rest? Genesis 8:4 says “and on the seventeenth day of the seventh month the ark came to rest on the mountains of Ararat.”
