Death of god theology is an idea about God. It says that the idea of God is not something that is real and that it is not necessary for understanding the universe. It says that we should not worry about God or look to God for answers because there is no God and we need to rely on ourselves to understand the universe. It is an idea that has been around for centuries, but it became popular in the 1960s. It suggests that humans can be more in control of their own lives and that we don't need to rely on something outside of ourselves to make sense of our lives.
