I like the angle, Insane. So God is not a 'thing'? God is 'nothing'? 'No-thing?' I suppose it depends on what you mean by a 'thing' and if God was in fact created. My understanding is the argument is that God was always there. So perhaps matter has always been there too, so it was never created. It just existed. Always.
Jon,
Even nothing is something. It has a name and a shared belief in its existence. What we perceive as "nothing" is more likely equated to a "stage". I wanted to find better words but I don't know that they exist.
As for your argument about God being nothing or no-thing, you are applying limits that exist in what we perceive in our reality to a being, for lack of a better word, that exists beyond such things. Basically you're framing your argument into a context you can understand even though it does not apply to the true nature of what you compare in your argument.
Watch this
We figured out how to prove the third dimension by making observations of two dimensional objects. Take any piece of paper and observe its shadow as you turn it, you will have your evidence that it is three dimensional from the way the shadow changes. If you want proof of what is beyond the third dimension, you will have to figure out how to see it's shadow. Otherwise, you'll have to live on faith on this matter like you do the rest of your life.
You have faith in the restaurant worker to properly prepare your food, faith in your fellow drivers to maintain control of their vehicle, faith in your police and fire services that they will come to your rescue when needed. Just as you have faith in the existence of God, either to the positive or the negative as the case may be.
Until science can prove rather than simply theorize, there is no more standing for the position of atheists than for believers. Even the Big Bang and Expansion theories fail to address the origination of our existence; they merely pick up shortly after to explain part of the "how" by making deductions from the evidence we are able to collect and understand. Believers like myself choose to recognize aspects of our life as indicative of God by analyzing a confluence of events that is at best improbable on their own. Atheists choose to refute this as evidence but have as yet to define or accept any evidence that would satisfy their argument. The basis of proof for each side is likely to never agree so these arguments serve no point in my mind other than poke back and forth with each other intellectually.
None of this argument is intended to support religion or the practice of worship and who has or fails to have the "proper" method.
