It is a strange thing to catalog the conflicting theories as to what the first artists thought they were doing down there in the caves, because the truth is that, to this day, we do not know why we make art. In the end, art may not be our invention at all. It may well have appeared in history as it does in the life of many individual artists:as an outside call, a sudden flash of inspiration, an inner wanderlust exerting such a powerfull pull that ultimately we would have to say that Picasso got it wrong: the early humans didn't invent art. Art invented humanity.
