Do you ever doubt your atheism?

[Brian37]

I was only relaying what struck me as the vague notion of God outlined in classic philosophical disputes and the similarities exhibited in certain scientific discoveries, such as 1) the apparent reality that something is eternal and outside of both spacetime and matter/energy, whether we call it a multiverse, a quantum foam or vacuum state (I have to brush up on the "Big Bounce" theory Diablo linked to so that might discredit the notion of a "first moment in time"), or 2) that determinism might ultimately bow to indeterminism (freedom in the truest sense, which God was often alleged to be). My use of the word God carries no connotations of ancient superstitions any more than theoretical physicists use of the term "God particle" for the Higgs boson does. God to me just amounts to something at bottom ineffable, a reality beyond the grasps of physical science because it may not (or it may) be describable in physical terms; it may not even be physical. I'm saying that neither I nor anyone else can state dogmatically either way until everything that can possibly be known is known, and I'm rather pessimistic as to whether or not that is even possible given our status as: one species, with one kind of brain evolved in a specific environment to perform particular functions, in a Universe that seems infinitely big and yet may only be the size of an atom in comparison to a reality far larger.

You don't simply mentally masturbate. Before you present an argument to someone you collect data that is established, you test that data with control groups, then you turn your findings over to independent sources to see if they come up with the same answer. If they do, then you are onto something, if it is knocked down, you start over and try to find the error in the data or methodology.

Vagueness is never a way to start thinking.

"Ideas must be distinct before reason can act upon them" Thomas Jefferson.

You have tons of competing claims about what a "god" is and no human to this date can empirically prove even the necessity of one. Science on top of that is pointing away from a god.

What ifs in science are thought out and reasoned backed up with prior scientific method.

I would simply take the most likly answer which is people like the idea of a god and make them up for a placebo comfort to avoid facing their finite existence. Psychology and even neurology and biochemistry and evolution explain to a much better degree how humans can make bad claims and come to bad conclusions.
