I believe that people seek out religion because of the things in life that we cannot explain. Nature and life is so extraordinary and intricate. I personally cannot accept the fact that we human beings and nature could have been created from something as simple as a Big Bang. Only a God with love and complexity would be able to create life. Also for example in Hinduism karma and reincarnation help answer the unexplainable. The question of what happens after death. Many religions help answer that questions. For Christians it is Heaven and Hell. For Buddhists it is also reincarnation.
Nature itself is a key foundation in Taoism. Taoists believe that we should not obstruct nature but that we should harmoniously flow with nature without disturbing it. Back then they didn’t have the technology that we have today. They spent most of their time experiencing nature. Through that experience that believed that in order to fully understand life they must achieve enlightenment, by immersing themselves in nature the came to the understanding of life and the significance of nature.
