I don't know, I'd like to think that this brief four score years or so isn't all that life is.Call it what you like, but do you believe in it?
However, whether there is a creator to it all which neatly fits into a definition of god which you seem to keep on harping on about is a different concept and is one which IMHO is of insignificant value or indeed purpose.
Whether this "god" has directed us to behave in some kind of conducive manner which necessitates some curious actions and setting up big buildings and attacking others who don't want to play ball in a particular way is a different issue. It's these forms of collective behaviour which I have considerable misgivings over and believe, ironically, has very little to do with the faith to which I'd be inclined to subscribe to.
I honestly don't believe that a god has ever come down in any form, nor has given messages to any prophet. Thus the concept of a formal religion is contradictory, irrelevant and unhelpful.
