I first off want to say, that this isn't any kind of "calling out" of anyone--and although this is directed mainly at you, SPrinkZ, this should not in any way be taken as a personal attack. I just want to clarify some things, as you pretty much just came in a couple days ago and started arguing with us, making completely baseless assumptions about our beliefs.
Also, I would like this to remain civil. Let's leave insults out of this thread, else I would like to ask that it be locked in such a scenario.
The problem we seem to be having with SPrinkZ is that we have not defined "god" yet. We are arguing about two separate entities.
So let's do that--define the "god" we're arguing doesn't exist.
When one of us says "God doesn't exist," we are probably talking about the Abrahamic god. That is, Allah, Yahweh, or the almighty nameless Christian "God." A personal god that is concerned with everything that we mere mortals do; he watches everything everyone does, he reads our minds, he listens to and answers prayers, and performs miracles (If all of these are "in his will.").
This god created the universe in just a few days, less than 10,000 years ago, although the geological, archaeological, and astronomical evidence tends to show overwhelming evidence that the universe is much, much older. This god also created humans before the animals, which means that dinosaurs had to coexist at the same time as humans at one point--however, again the geological and archaeological evidence is also strongly against this one.
And I could go on, but we'll move on unless you need a further description of this "God".
Your arguments seem to be about a different god, however. A simple divine being that created the universe and pretty much left it at that. Pretty much a deist point of view, am I right?
Perhaps now you understand the biggest differences in what we are thinking about? Do you think that the likelihood of these two different types of "gods" are the same?
I don't think so, and most everyone else here will agree. It is possible to be 100% positive that the former, Abrahamic personal god doesn't exist. Evidence against this god is all around us, and the evidence supporting this god is incredibly lacking.
However, you are mostly correct that your idea of "god" is less able to be contradicted, but that doesn't not necessarily mean that it can't be shown that it almost certainly does not exist.
The thing with your idea of god, is that it exists outside of our plane of reality in some outside (for lack of better word) universe. The problem that comes up with your god, is that sure it seems very unlikely for our universe to have existed out of "nothing" without some divine help, but what about this god?
As unlikely as our universe having come from "nothing," just how much more likely is it for this god to have just simply existed? As complex and unlikely as our universe is, this god is infinitely more complex and unlikely. Beast should be able to take this argument up from here, but I will continue with one more thing.
It is not a matter of black and white, "either it exists or it doesn't," 50-50 chance. The likelihood for the Abrahamic god is no more than that of Zeus, Hera, Aphrodite, Poseidon, Wodan, Thor, Isis, Brahma, or Kali. Is that something we can agree on? They're all equally likely as a fairy tale.
The likelihood of the deistic god is not black and white, 50-50 either. Just stating that "we don't know how the universe started, so it is entirely possible that a god must have done it" is not a rational mode of thought. That is no different thinking from the ancient Greeks not knowing how lightning formed, so giants forged the bolts of lightning for Zeus to use as weapons to slay his father Cronus. It's the same as the Greeks thinking that the gods moved the celestial objects themselves, because they didn't understand the physics involved. It's the same delusion that the unknown must be the cause of the divine.
While I do realize that the existence of such a god is very, very difficult to disprove, if possible at all. But the likelihood of such a being is definitely not 50-50, "either it exists or it doesn't". The probability of such a being is not very high.
But the nature of our atheism is not that it is impossible that such a being does not exist! Do not make that assumption, as we have told you the opposite many times already although you don't seem to understand it. If evidence in favor of such a being was discovered, all of us would examine it and make the necessary changes to our beliefs to accommodate the new evidence. But until that time comes, we will indeed be very skeptical about such a being's existence. Skeptical to a point where we do not believe that it is likely for such a being to exist, and live our lives accordingly.
