Why it incorrect to say that insulation keep out the cold?
Because in science, cold doesn't exist. You can't make cold, you can only remove heat. But in human language we've made words to describe the absences too. Dark is the absence of light. Cold is the absence of heat. Vacuum is the absence of all material. So insulation can't keep the cold out, since the cold doesn't exist. What you can do though is keep the heat in. Heat is a real thing. You can make heat.

What is one thing that helps keep earth warm?
Aside from the sun, one thing that helps keep the earth warm is something called the "heat of fusion" not to be confused with nuclear fusion, as the earth's core and mantle slowly solidify, turning from a liquid into a solid, heat is released in the same way that heat is released when water turns from a liquid to a solid. On geological scales, this process helps keep the earth's interior warm.

Why is news paper good at keeping stuff good and warm?
Heat passes from the warmer thing to the cooler thing, if there is a way for it to pass. Anything with lots of air pockets does not let heat through easily, so newspaper, cotton wool etc. are good in keeping things warm. They neither let heat out or in, so they keep the warmer thing warm and the cooler thing cool!
