Let’s suppose, as most religions do, that God is the creator of the universe. However, this implies the assumption that God is not part of the universe itself. But this breaks the common definition of universe that states that everything is included in the universe: universe includes all existing things, either seen or unseen, from the past, present or future.
So, let’s rewrite: God is the creator of the created part of the universe. In this case God is included in the universe itself. Just that one of its actions is that of creating other things inside the universe.
As God is then just a part of the universe, it cannot be the creator of everything! It’s obvious he didn’t create himself. Maybe a Master God created God, but in that case we can just switch back to the first paragraph, replacing God by Master God and looping again, indefinitely. If we do so, we would admit having infinite master gods outside our universe, and we would need to think about the universe as the limit of a set of master gods when their count number gets infinite – isn’t this just advanced Maths?🙂
Anyway, in this case, we get outside of the loop by putting our brain to work, and therefore (just like in Maths) we can use a logical concept of infinity to thing about a single God containing multiple entities that are subsequent creators. This way we reach, again, to a single God concept, this time inside an infinite universe: all gods can be considered as part of the universe, if we accept that the universe can contain an infinite number of entities inside – and an infinite universe is a grealty accepted concept, we don’t have any trouble to accept that.
Now, that we have only one God (possibly, including infinite entities inside) remaining, what’s the difference between God and humans? They both create things inside the universe. They both may have been created by (a part of) God.
In other words, God is actually not important in the universe. It’s jut a part of the universe, exactly as humans. So what’s the point of religion (or faith in God), outside of being a social behavior mediator (and outside of being an important mass manipulator :-))? Shouldn’t psychology (and, respectively, mass media) be enough for that?
