Thank you for your response. You make a good point.
Many non-believing scientists take the view that the universe is based on natural laws, but do not give a rational explanation for this understanding.
In my view this is a philosophical question. The problem is not, Does God exist?, but, Can we have a universe governed by rational natural laws without a rational Creator of the universe? I would say No, but that needs to be discussed. To answer this question with a No does not definitely “prove” the existence of God, only that a rational universe requires a rational God.
I think the New Atheists understand this, which is the reason that they say that the universe is not rational, thus God as rational Being does not exist.
Is the universe rational because God is rational, or can we say God is rational because the universe is rational? Is Christianity rational because God is rational or because the universe is rational? What does it mean to be rational?
