Why Do People Link Spirit With Religion And Fail To See The Supreme Power Of The Universe?

It is a general trend that if someone does not follow a religion they are called atheists, which is someone who does not believe in God. When quizzed about it, however, many will admit they recognise that there is some kind of power working but they are not accepting of religious gods. They are more than interested in explanations of the Spirit of the Universe and how it is in all things and people while controlling the world.
