The Almighty told Noah to git his whole fam-damly into the ark, cuz he was the only dern good feller around. Take seven pairs of the clean animals, a male and his woman, and just one pair of the unclean. And don't forget them birds - take seven pairs of them too, male and female, so they can have babies later. The Lord was plannin' to send rain for forty days and nights, and every living thang would be wiped out 'cept for Noah and his bunch.
Noah did exactly what the Lord done told him. When he was 600 years old, the flood came and he, his missus, his sons, and their wives all got in the ark. They brought two of every kind of animal, male and female, just like God done told 'em to. After seven days, the flood came and lasted for forty days and nights. It covered up every dern mountain on earth, and all the critters and humans drowned 'cept for the ones in the ark.
The flood lasted for 150 days, and when it was over, the only thang left on earth was Noah and them in the ark.
