Huh? The atmosphere is just air that gets thinner as you move away from the earth.

I suppose what doesn't make sense is what keeps the atmosphere from escaping into the vacuum of space. That is because most people's idea of a vacuum is a vacuum cleaner, which sucks things up. It gives the impression that the vacuum of space should suck the air off of the Earth. But what physics teaches is that there is no such thing as sucking. That is, the vacuum cleaner does not pull in air. Instead the pump in the vacuum pushes air out of the vacuum cleaner through the exhaust vent and that lowers the air pressure inside the cleaner. Then the higher pressure air outside pushes its way into the cleaner through the intake vent to which you attach the hose and cleaning attachments, blowing dust along with it. The Earth's air is attracted to the ground by gravity and a thick layer has built up. The weight of that layer causes pressure.

Actually your not inside space until you've "broken" the atmosphere. Breaking the atmosphere means simply that you are no longer in the reach of Earth's Oxygen or other elements, and the UV block around the earth. There is a good chance of burning up while breaking the atmosphere because of the intense friction along your spaceship from the air. It's really simple.
