(Earth's atmosphere ----*******#####):(:):)XD rofl :)

The earth's atmosphere is much different than the moons. For one, all objects that come into earth are usually burned up due to our atmosphere. The atmosphere is earth is made up of 70% nitrogen, 21% oxygen, and 1% of other gases like argon. Our planet, Unlike others, also contains life. Our atmosphere protects us from the sun and gives us oxygen to breathe. Its pretty cool that there used to be no oxygen at all, but tiny bacteria converted the carbon dioxide into oxygen. The moon has very little atmosphere. Caters and footprints are still on the surface of the moon because there is no forces to erode them away. The is also no water on it to sustain life. Because of extreme atmospheres found in the other planets, no planet but Earth has intelligent life on it. No life that we know of anyway. Earths atmosphere is what makes life possible on Earth.
