Why does evaporation occur?

I know that liquids can turn into gases via boiling, but why can liquids turn into gas *without* reaching their boiling point?

By the way sorry if this question sounds stupid.

Temperature isn't really a fixed value of how much energy molecules have, it's an average. This means that even at a temperature well below the boiling point of a liquid there will be some molecules with enough energy to break off into the gas phase and so the liquid evaporates.
