The atmosphere has stuff to do with gas. If the temperature was low enough though, would the gas fall down as liquid? (kbin.social)

Side question. I always thought that it was colder in deep space than anywhere near a star. What about earth causes things to naturally (not talking artificial stuff like freezers) get cooler than places in space that have no heat source?

Naturally occurring? Yeah space wins. But artificially? The hottest and coldest temperatures ever recorded were here on Earth in a lab. Here's a cool infographic about it. The TLDR of which is the coldest temperature was -273 °C and the hottest (currently -- the early universe was hotter) was 5.5 trillion °C both on Earth.
