The point of view of science is that God does not exist. This is the natural conclusion of an endeavor which takes into account only quantifiable measures. Consciousness of any sort is not quantifiable. It is a "phase space" construct logically congruent with quantitive measure but not identifiable by it.
We know that our consciousness exists by our personal observation of it but we cannot transmit that knowledge to others by any quantifiable means. We merely state that we observe our consciousness and assume that others do also report faithfully what they observe. It is never proven as in a mathematical proof.
Such is the case with God, the hypothetical mind associated with the universe as a whole. We can never, in principle prove the existence of God by logical/mathematical/physical means. His existence is only implied by extension from the existence of our own consciousness which is "proven" only to each individual through self-observation.
The rational is as follows:
In short, if the universe is not a conscious entity
The argument then concerns the exact arrangement of physicality and consciousness for the universe as a whole.
Is God a "personal" entity, i.e. someone you can appeal to directly?
Since, by the forgoing reasoning, no definite answer is possible to this question, I will simply examine each as though true.
