Ok, I'll bite.  Firstly, you start with a couple of premises that are not or were not universal when most modern religions established their various dogmae.  Early religions believed in an all powerful God (s ) in the heavens with the physical universe being limited pretty much to the finite earth.  That is, one had to join the diety in order to transcend beyond the very limited universe.

We now know through science, that our savage ancestors got this part wrong.  We know that the Universe is infinite and we know that there likely are other beings populating it.  Some would likely be more advanced than we, and others more primitive but we are likely still fairly primitive.  We therefore could be considered emerging in that we can conceive of things beyond our understanding and know that we must change our various theories to fit the facts we find and not vice versa.  

I submit that none of us understands the true nature of God or his will.  I further submit that it is entirely possible that those of our primitive ancestors who claimed in writing to cement his laws and the " Facts " that came to be known as the bible or various other religious texts were in error.  It is certainly possible that alien beings were mistaken for gods and that their teachings were incorporated in these various documents.  Does this mean that there is no God?  Certainly not.  It does however mean that these various texts were penned by people who were primitve.  They did not understand the world around them or various technological achievements that we now take as commonplace.  They would therefore describe them in mystical language as they would perceive them as magic.  

My suspicion is that God is larger and more powerful than anyone is truly capable of understanding anywhere in this reality and quite simply we do not know what we don't know.  Faith or not, God is out there but might not be what has been reported in such limited terms.  

The real kick in the collective human ass, will be the day we find out that we are not really the center of the universe, just a very small corner of it.
