There is a “fire” that warms our skin by day. That “fire” is burning some 93*million miles [150*million km] away! What power the sun must have for you to be able to feel its heat from such a distance! Yet, the earth orbits that awesome thermonuclear furnace at just the right distance. Too close, and earth’s water would vaporize; too far, and it would all freeze. Either extreme would render our planet lifeless. Essential to life on earth, sunlight is also clean and efficient, not to mention delightful.
Creative power is evident in every facet of the earth’s design. Consider the atmosphere, which serves as a protective shield. The sun emits healthful rays and deadly ones. When the lethal rays strike the earth’s upper atmosphere, they cause ordinary oxygen to turn into ozone. The resulting ozone layer, in turn, absorbs most of those rays. In effect, our planet is designed with its own protective umbrella!
That is just one aspect of our atmosphere, a complex mix of gases ideally suited to supporting the creatures living on or near the earth’s surface. Among wonders of the atmosphere is the water cycle. Every year the sun lifts up by evaporation over 100,000 cubic miles [400,000 cu km] of water from the earth’s oceans and seas. The water forms clouds, which are circulated far and wide by atmospheric winds. This water, now filtered and purified, falls as rain, snow, and ice, replenishing water supplies.
