Nobody makes gases. Gases are natural.
The gases in the atmosphere
gases
These gases are nitrogen, oxygen, argon, other noble gases, carbon dioxide, water vapors.
compressibility
liquids and gases have almost the same molecular structure which makes the alikw
Noble gases have completely filled octet. It makes it difficult to get unstable.
Gases are compressible.
The mixture of gases in the atmosphere are a solution of gases. Since nitrogen makes up 78% of the gases in the atmosphere, it is the solvent and the other gases are the solutes.

A full octet makes the noble gases nonreactive.
