It is impossible to live in a "BOX". I dare you to try to put boundaries around it all! All: universes, black holes , dog holes , shit holes, strings, and what ever science thinks of. God is for myself not a being, a he , she or even a IT. After all , we just luuuuuv boundaries.
Over the years there has been many of arguements regarding this very subject, I for one dont believe there is a god, and if there is then we either have many religions who are wrong, OR all religions are right, but are fighting over nothing cause surely there can only be one god, no?! End of the day this is all to do with what you want to believe, everyone has a different opinion, and my mind is made up...
