Being science can neither prove or disprove the existence of a God.. When two opposing people argue about a God existing, aren't they simply arguing on their belief about a God existing?
Neither is arguing with support of science or scientific evidence.
My post isn't about the bible, a flood, prophecies, abiogenisis, evolution, the big bang, etc. Its simply and strictly about "a" God existing or not existing.
Yes of course. Science can't have anything to say about God, since nobody can agree on what observable properties or consequences, if any, there should be, if there is a God. (Post 8 refers)
Belief or otherwise in God is a matter of a person's worldview, which is a question of metaphysics rather than science. On one side you have the physicalists, who extend the principle of scientific scepticism to take the view that only things for which there is reproducible evidence should be taken as real. This seems to be more or less the position of the "New Atheists": people such as Dawkins, Dennett and Peter Atkins. On the other side you have those that think there is, or may be, more to the world than that, even if the the only "evidence" for it is vague feelings that are subjective and personal.
Either way, "proof" is out of the question.
And, by the way, as science does not deal in proof in the first place, science is always going to be the wrong tool to use in any attempt at proof.
