Humans are curious by nature and have always looked for answers. From the beginning religion answered questions about the things that could not be understood . The sun rising, and moving across the sky and setting. Of course it was being done by a powerful being that gave them light and warmth so they praised and thank it, rain, snow, famine, death, dreams, love, thunder, lust we’re all things controlled by “gods” who were in turn thanked(worshipped) in an attempt to influence them to show them good fortune or to bring bad fortune on others. Being curious we eventually were able to explain all the things that the gods did through science and they fell away, until there was just one and that one still answers the questions we can’t really ever know the answers to why we are here, and what happens after we die. All the ancient “religions “ had gods that all had similar functions Babylonia , Sumerian, Aztec, Egyptian , Chinese, Greek etc… sun, love death underworld war light etc…
