Where did love begin? What human being looked at another and saw in their face the forests and the sea? Was there a day, exhausted and weary, dragging home food, arms cut and scarred, that you saw yellow flowers and, not knowing what you did, picked them because I love you? In the fossil record of our existence, there is no trace of love. You cannot find it held in the earth's crust, waiting to be discovered. The long bones of our ancestors show nothing of their hearts.
