I thinkbit might be like that kid's experiment. You disolve different amounts of sugar in to 3 different samples of water. In each sample you add a different food colouring to the solution.
The liquids separate into layers by density, but that doesn't mean the lightest liquid floats away out of the cup (again excepting evaporation). Gas might be similar? But perhaps not as otherwise perhaps we'd end up with different layers for nitrogen/oxygen/etc.
What doesn't stop that happening? Weather axing as a mixer? If so, how do the light gases not remain stirred in?
All excellent questions you are leading to.

The atmophere isn't a vacuum so the reason the liquids stay in the container is because they're still denser than the gasses above it. And if "space" were filled with gas or some other substance that's lighter, even if its the "ether" then that works; or if there's a barrier. But not if its a vacuum like we're told.
The gasses are stirred in the atmosphere but still tend to orient.
