My definition of 'god' follows the meaning of people like Einstein and Stephen Hawking and Richard Dawkins, even though Dawkins himself avoids using the g word. God is the unexplainable. It is everything in the universe that cannot be explained. There is no living consciousness up there who is watching over the entire human race, listening to our every thought and watching our every move.
But think about it. Even if there was, would you want to worship a being that condemns you to an eternity of torture and pain and suffering just because you don't do what he says? I know I wouldn't. The biblical definition of god is an abusive parent with a childish yearning for control and power. Who in their right mind would want to praise that kind of behavior? The beauty of being an atheist is you don't have to live in fear of eternal damnation. You can live life to its fullest.
