The earth's air is made up of about 21% oxygen, 78% nitrogen, 0.03% carbon dioxide, and trace amounts of other gases. Chemical reactions within plants and in our upper atmosphere maintain this exact balance of 21% oxygen to 0.03% carbon dioxide. For life to exist, this balance must have been maintained from the beginning! If oxygen levels were higher by as little as 4%, increased fires and extensive oxidation reactions would make life on Earth difficult–if not impossible. With even a slight change of the carbon dioxide level, the earth's temperature and plant growth rates would be radically affected.
If would seem that the very composition of the air we breathe has been designed specifically for our benefit. It takes incredible faith to believe this could have happened by chance.
