물이 지구와 생명을 창조하였다
Water Create Earth and Lives
초록
Water must be readily available to support all lives life and to create our earth. At first thought, It may seem that water is always available, since the earth is literally surrounded by water, so called water planet. The manner in which water circulates between earth and atmosphere determines where ample water supplies can be found and used for all organisms. If no forces except gravity were at work, the earth's water would settle in to the ocean basins and remain there.
