We're told by some that the Universe is fine tuned for intelligent life, particularly intelligent human life is the implication.
This fine tuning is evidence of God, so the theory goes.
So, the story goes, God created the Universe in a way that would foster intelligent life.
We're not sure how big the Universe actually is, but we do know that it may be at least bigger than 156 billion light years across.
And, it may even be getting bigger.
So, here's the question? Why did God make the Universe so big? Clearly, there's no--and never will be--interaction between intelligent life on Earth and what's happening on the far side of the Universe. From our intelligent life standpoint, who needs all the space and stuff 100 billion light years away?
So, to those who embrace the fine tuning argument for the existence of God, was it really necessary to the fine tuning in order to create intelligent life that the Universe be so big? Is intelligence so difficult to fine tune for that something perhaps of infinite size and infinite energy and infinite time was required? Surely, God could have achieved all that was needed to fine tune for intelligent life in something not much bigger than our solar system, or maybe the Milky Way Galaxy. But these are tiny things compared to the whole Universe.
So from a religious / Genesis / fine tuning view, why is the Universe so large?
