Ancient cosmology saw the universe as turtle shaped, with a flat Earth covered by a dome-shaped sky. For others neighbors, the world was the result of a mighty battle between warring gods.
Here in this book there's only one god and only one stone (the creation stone) and he creates simply by speaking to the Stone.
The stone continues to bring to life and structure to all parts of the universe. The sun, moon and stars are not to be worshipped as divine celestial beings because they are created things, along with everything else.
The creatures of the sea and the sky are blessed with the same stone the creator used and will use for humanity.
All the areas if the universe have been filled except for the land. So it happened at the twilight time the creator took the stone, filled it with his warm breath and the mist caused by his breath became water droplets on the surface of the stone. This water droplets fell to the ground and became living cells. So the creator took it and gave it form with some added attribute to aid humanity survival.
