At the dawn of time, there was a first contact between man and the environment. At that time things had no name. The water of the river flowed without ever having been heard, and there was no way to define with a word the effect of light generated by lightning across the sky. Human beings began to define themselves, chose gods, made an agreement with nature. There was a day, a time, a light, in which living beings that had never seen each other before, met for the first time. We were witnesses of time, of the seasons. The life and death of the sun before our own. That capacity for wonder still occupies a place in the tunnel of our memory. We can recover it.
