Back in them olden days, when folks started poppin' out babies left and right, them heavenly critters took notice of the fine-lookin' womenfolk and decided to hitch up with 'em. The Almighty himself declared that folks weren't gonna be livin' forever 'cause they's made of flesh and blood, and only gonna make it to 120 years.
Now, in them times, there was some big ol' giants walkin' 'round, and they wasn't no ordinary folk. They was the offspring of them heavenly beings and human gals, and they become the big shots of them times, known as the ancient heroes.
But things got real bad, I mean, downright evil, and the Lord felt mighty sorry he ever made humans. So he decided to wipe out everything, every critter from the ground to the sky, 'cept for Noah and his kin. You see, Noah was an upright feller, and the Lord saw fit to spare him and his fam.
The Lord told Noah to build an ark, a great big boat to save him, his family, and a pair of every animal from the coming flood. The boat was to be 450 feet long, 75 feet wide, and 45 feet tall, with rooms and a door and everything.
And so Noah did just as the Lord commanded, and he gathered all the critters and the food they needed to survive. And when the flood came, Noah and his family and all the critters on the boat was kept safe and sound.
