Why is there no air in space?

pu1. There are many different gases in space. It's just that gravity is so big that it has to be so big that it has to be so big that it has to be so big that it has to be pulled

OK

pu2. The universe itself is rich in plasma. Continuous heating of gaseous materials produces a collection of particles made up of ionic nuclei and free electrons, which is plasma, so there's already a lot of plasma in the universe that can be a gas

OK

pu3. If you look at the empty space itself, there will be no air because there is no mass. A planet big enough to pull because of its mass will take the gas. Or there are times when it's just a nebula

OK

pu4. There is a lot of air on Earth, but there is no air on the moon because the moon has a small mass and small manpower, so it is not enough to hold the air

OK

pu5. Isn't there a tiny amount of oxygen and nitrogen like Earth in the universe? Since it's so wide, it's just low in density

OK
