Artists make art, but it isn't because their creations have a point. Artists create because, thousands of generations ago, our ancestors climbed down from the trees and decided that drawing on the rough stone walls of the caves where they dwelt was a productive use of their time. They took a useless activity and gave it usefulness and meaning, and that meaning went on to inspire new generations of artists. Humans would begin to experiment with new ways to make art, new surfaces upon which to draw, and each new artist would add something to the collective value of art as a whole.
