because the earth has mass enough to hodl gasses attracted
the force of gravity as all forces works with the inverse square, and that is because the universe is 3 dimensional

so gravity will be much stronger close and 10x weaker at a distance that means that at e certain point earth is not going to have enough mass to attract gasses, so the atmosphere is what it is

typically in space you have "radiation" - changed particles - particles stripped out of their pair particle so they are charged

bigger planets have bigger atmosphere, venus similar size planet have similar size atmosphere, different composition

gravity is the weakest of all forces, the electromagnetic force that makes electrons orbit protons makes it impossible for gravity to squish things, but gravity adds up, and you can get to a point where all is squished

you are able to move because all molecules in your body work with electromagnetic, technically chemistry is just the exchange of electrons
