How very astute. Fluids form mixtures and circulate based on different things, like pressure and heat.
But the gases do form layers. Who said they don't?

Gasses do not separate into clean distinct layers because there is always mixing taking place due to wind and even random motion of gas molecules (i.e. diffusion).
But still, heavier molecules do tend to sink, so there is a measureable higher concentration of heavier gasses near ground level.
For example, it is well known that gasoline vapors accumulate on the floor/ground during a spill.
Also, this is why gas centrifuges can work for separating uranium hexafluoride gas into U235 and U238.

Oh but they do!
the different layers of gases such as the atmosphere, ionosphere, stratosphere, etc. all have different mixtures of different gases, according to their size and weight.

Have you ever heard of the ozone layer?

they do you just can't see them. there is layering, but it is also constantly being mixed.
