It all depends on what meaning you put into the word “God”
It is a word to express "something" you do not know but are trying to attain. Well, if you have received a religious education, you are accustomed to call this "God". If you have received a more positivist and also a more philosophical education, you are accustomed to call this by all sorts of names, and you may at the same time have the idea that it is the supreme truth.
