When we look at a picture of our univers taken by the Hubble telescope, we can see that there is a lot of stars just like our sun out there. There must be some habitable planets like our around some of them. So if theese planets are habited by intelligents being, are they praying the same gods as some of us are. WE the habitants of this earth can't even pray the same god, imagine the univers, If I were to beleive in GOD, I would have to pray so many of them that I would not have time to do anything else.
So I can only say that until proven otherwise, God does not exist.
