I believe that grass is usually always green, unless the sun or fire burns it into a different colour. Is my belief in the colour of grass the result of my not believing in God? Or is it merely a statement of truth about something that can be clearly observed by one and all? Why do we have to believe in "other things" if we don't believe in any God? Theists have this distinct 'thing' about people needing to believe in something or other, as though not believing in any deity is somehow abnormal or goes against nature. Why is that?
