But the atheist can avoid the whole God thing by simply denying that the universe (or multiverse, perhaps) has a beginning to its existence and so "no one created the universe".
You've touched on the prime reason that there currently isn't an answer to the "God or no God" argument. Mankind places beginnings and endings to everything as an absolute. To man, all things must have an exact place in space that is an end and an exact moment in which time started in all events. This is the problem between the two factions present in this seemingly endless debate.
The sky-pixie bunch use their omi-whatever being to fill any absolutes that are missing in the equation. The absolute swinging anti-sky pixie bunch use the same amount of logic in sternly commanding that there can not be any such thing as a super being.
I do love to watch you guys argue. The reality of the pointlessness in the argument is that which neither of you apparently see, (unless you argue for nothing but practice).
The obvious avoidance of those arguments of logic that show the absolutes in either side are, in themselves, an avoidance of the truth of the matter. That truth being that at this point in man-time, there is no answer to the absolute, regardless of the amount of argument.
A man blind since birth cannot say that "light blue" exists as seen by his seeing companions. Neither can he ever say with accuracy that "light blue" doesn't exist to them. Because of his lack of ability to ever have seen or to see "light blue", he'll remain ignorant of the outcome of the existence of "light blue" until he either has the ability to "see", as do his companions or gains insight to it's existence in some other manner that proves it's absoluteness.
Prior to arguing my above statements, examine them with your argument and see if your argument has already been discovered within my statement. It'll avoid my having to say that you should have read more closely.
But, by all means, keep practicing this argument. It amuses me.
James, so far, it seems that you're the only one in this instance to bring up a fraction of my point. I commend you for your fairness in logic.
