why is it much colder in the poles if the sun is so far away anyway, shouldn’t it not make any difference?

Answer 1

The distance to the sun has nothing to do with it. The poles are cold because of the low *angle* of incoming sunlight. “Daytime” at the poles is like evening or morning everywhere else, with the Sun very low in the sky and its light spread out over wider areas of land (meaning each area of land receives less energy).
