It is need to support life on earth especially the ultra violet solar radiation and from also in the heat index given by the sunlight. It provides us an essential gases like oxygens that we needed when we breath. And support the earth from the outer space where if the atmosphere are gone, people living in the Earth are experiencing gravity and travel to outer space until they will reach the well known "black hole" or the heat of the sun.
