What is the importance of gravity?
Gravity is crucial for humans to survive. It's because of gravity, the gasses such as oxygen, nitrogen, etc exist in the atmosphere. Without gravity, those gasses might have left planet earth long ago. Its because of gravity we are here on planet earth. Earth actually rotates with high speed. If there is no gravity, it is not possible for us to stay on earth. Moreover, the sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to use the sun's light. Thus without gravity, there is no life possible.
