You have a misconception... Pressure can be definitely exerted on gas. You might have heard of air compressor? Pneumatic cylinder? these elements exert pressure on air(Gas). Free air from atmosphere is sucked inside then pressurized & used for many applications.
Please go through working principles of these elements.
As the molecules in the gas move, they collide with the container they are within. These collisions is what we call pressure.
how do gasses create pressure? What are the three characteristics of gasses according to the kinetic theory
Burning rocket fuel exerts pressure on the rocket nozzle. Note that this happens regardless of whether there is any air for the exhaust to push against. It is simply a matter of expanding gasses which exert pressure.

All of the forces exerted by the individual particles in a fluid combine to make up the pressure exerted by the fluid.
The fluids in your body also exert pressure.
Fluids exert pressure due to the weight of the fluid above pressing down on the fluid below. The pressure in a fluid increases with depth because of this weight. This is known as hydrostatic pressure.
a. moving molecules that exert forces.
The earths winds
the earths surface.
Yes, all fluids exert pressure. Pressure is a fundamental property of fluids and is caused by the molecules in a fluid colliding with the walls of the container or object they are in contact with.
