I don't realize why an all-powerful and all-knowing god, in the mind-numbingly unlikelihood of its existence, would give a toss about whether we worship it or not. I would be a bit weird'd out and momentarily pleased if i realized the entire ant colony within a kilometre around me worshiped me as their god.
We are also much less than ants to a deity who literally has created a universe where there are 100 billion galaxies, and each galaxy on average consists of hundreds of billions of stars. Each star is billions of times bigger than we are.
So, why would a god who literally has created such a wondrous and huge universe, care about what a microscopically small creature in that universe prays about?
Finally, if i were a god, and had to 'judge' (Cause we're so important we get judged by this wondrous God, the self-importance is amazing we ascribe ourselves) me, I'd consider whether I respect other people and their choices, and whether I respect myself and tried to enjoy the life I had. Not whether I blindly tried to follow the wishes of a jealous, angry and murderous depiction of my 'creator.' In fact, the latter sounds a bit crazy.. doesn't it?
But thats the crazy world we live in. Instead of being nice and autonomous, we like putting our faith in things that don't exist, and if they did, it really shouldn't change our outlook on life.. but at least sanity doesn't lie in statistics..
