If man still had no understanding of the weather and what causes extreme weather events that destroys, or encouraged our crops, we might still have a call for religion. It must have been frightening to feel that crops were at the mercy of the elements. Before understanding of the inevitability (so far!) of death, the same must have applied to that. Now that most of that ignorance is behind us, we would be well advised to think for ourselves in navigating our future, rather than relying on a god or gods to do it for us.
