Flooding myths around the world

A man clearing fields found the trees regrown overnight. He found that his grandmother Nakawe did this, and she told him that he was working in vain because a flood was coming. Per her instructions, he built a box and survived the flood with corn, beans, fire, and a black bitch. After the flood, he would return home from work to find meals prepared. He spied one day and found that the bitch took off her skin and became a woman to do the work. He threw her skin into the fire and bathed her in nixtamal water. They repopulated the earth.
