The waters of chaos were a blessing in fact, that brought new life. Each year when the waters of the flood would recede, leaving a course of fresh minerals and nutrients in the waters, which would then cause the food to grow, and spring would be a beautiful time in Egypt, because of the waters of chaos. They celebrated the coming of the waters of chaos bringing the new life. They call that celebration in Egypt meaning 'Argha Noah', not the 'Arc of Noah', but 'Argha Noah'.
