If you check on the composition of air via google, you will find that air consists mainly of nitrogen and oxygen gases. Hydrogen gas molecules have a higher molecular velocity and can escape from the atmosphere to outer space more easily. (If you are not familiar with the concept of escape velocity, please google.)
You actually brought up an important concept. What are the factors governing the molecular velocity of gases?
The answer lies in their mass and the absolute temperature. In general, the lighter the mass and the higher the absolute temperature, the higher will be the molecular velocity. There is a layer of gas (atmosphere) on Earth because the escape velocity of many gases such as nitrogen, oxygen, argon, carbon dioxide is much less than the escape velocity. The moon has no atmosphere because it has a low mass and thus a low escape velocity. All gases escaped to outer space long ago.
In other words, the gravitational attraction force on Earth is responsible for maintaining the presence of our atmosphere. This leads to the second divine revelation – if we can bring-in the kinetic energy of air molecules, we may be able to bring-in the gravitational energy directly.
More on that later.
God gives us the almost inexhaustible kinetic energy of air molecules. God also gives us the equally inexhaustible gravitational energy on Earth. Can we understand and use them? Amen
