My journey from rabidly- Irish-Catholic-obnoxious- little prig to atheist took 20 years. It began when I actually read the bible and began to notice some of the more fatuous catholic beliefs for the nonsense they are. EG the virgin birth, infallibility the pope and the unshakeable belief masturbation is a mortal sin. I mean,it’s one of the few things in life at which I have truly excelled.
All religions and are definitely man made. Imo, without exception, every religion reflects the people who invent it and the individuals who practice it.
As for ‘an urge to the divine’, I’m not convinced this is 100% man made. I say this because some form of religious belief is virtually universal. It certainly meets some important human needs.*** I also suspect religion may have some evolutionary value, but I can’t prove it.
One of my favourite graffito: “Religion: Man’s attempt to communicate with the weather” (anon)
***such as; addressing the fear of death, giving the illusions of a meaning of life and of control, over life. Traditionally, religion has given a sense of community and the protection that can entail. Even today, there are countries in which religious belief can be a matter of life and death . I don’t just mean Saudi Arabia and other small Arab countries. Other countries include parts of Africa and India.
