V32- And We made the sky a well protected roof. Still they turn away from its signs.21-The Prophets, V32[21- SURE AL-AMBIYA, V32]The atmosphere is a gaseous envelope of 10,000 km surrounding our planet, invisible to the eye. Millions of meteorites of varying sizes keep falling from space in the direction of our world. Despite its transparent structure, our atmosphere puts up a bold front against this meteorite bombardment like a steel shield. Had it not been for this feature, there would have been no life on earth, and our world would have been riddled with holes. We witnessed a sample of it when we landed on the moon. Meteor showers kept hitting the surface and the meteoric bodies of greater volume penetrated the crust of the moon, digging deep holes on it. Meteors strike the molecules in the atmosphere with a great speed, and the heat generated turns them into dust particles before disappearing meratol in the air. The atmosphere also has the function filtering the harmful rays of the sun, protecting life on earth against extinction. This ingenious design partially absorbs incident electromagnetic radiation. Thus, the atmosphere filters the rays harmful to life while letting the rays that foster life on earth pass through. The heavens perfectly perform the duties and functions apportioned to them by God, and unfold before the eyes of those able to discriminate intelligent and teleological creation. The verse refers once more to the dogmatic disbelievers blind to these marvels. All these formations in the atmosphere show the design behind them, namely, the creation and perpetuation of life. The approximate temperature in space is -270 degrees Celsius. Our earth is protected against this cold thanks to the atmosphere. The atmosphere prevents the energy directed to the earth from going back to space.
