Gods have always been used to explain what humans don’t understand. There used to be a god or goddess for everything. Then science came along, and, bit by bit, we learned how the world works, so we no longer need gods for rain and sun and harvest etc. All that is left is two questions: “why are we here?” and “what happens after we die?” It is fear of meaninglessness and mortality that keeps faith alive. The saving grace of religion is that it has been responsible for a lot of really wonderful art and architecture over the centuries. Here is some Hindu art from Hampi and Badami, in India.
