A vacuum is just a (near)-absence of anything that has mass and occupy volume...gases have mass and occupy volume, thus gravity has an effect on gases as it does on us.
A gas (high pressure) will always fill a vacuum (low pressure) until pressure equalizes. You can't have the two next to each other.
Fun fact: this is also how vacuum cleaners work. A pressure drop is created within an inner chamber that forces the air outside (higher pressure) to rush into the vacuum cleaner.

Gravitational attraction between the gases in our atmosphere and the Earth prevents this from occurring.
You know how farts smell less as you move away? That's how the atmosphere works
