The ozone is made from oxygen, but for billions of years there was no actuall oxygen in the earth's atmosphere. The earth's primitive atmosphere is said by scientist that it was composed of water vapor,carbon dioxide,sulfur dioxide, nitrogen,and other gases released by volcanic and other activitys from the planets hot interior. Because there was no oxygen, there was no ozone, and all the sun's ultraviolet radiation reached the earth's surface. THis ultraviolet radiation had enough energy to break up any complex molecules that may have formed and prevented complaex livefrom developing. At a certain depth underwater, however, just the right amount of ultraviolet radiation was screened out.that is the same radiation that probably led to the creation of primitive life forms.
