I think that you need to have information to assign probability, and since you have no information you can not realistically do so.

Also to get useful information out, you also need to specify which god or gods, you can not treat them as a group because they are too diverse. For example if you ask me about the Christian biblical god, I would say zero, because it is impossible. On the other hand if a religious naturalist told me that, since they do not believe in anything supernatural, therefore nature stands in as a god for them. Then I would say that if I accept you basic premise. Yes fair enough.

The main "fallacy" is your question. There's no such thing as a "probability;" as an agnostic, I recognize since each person's definition of 'god' differs, the physical world either magically appeared out of nowhere, or there a basic fundamental Explanation for where it came from. Since we cannot do so at present, and may never be able to, how could we ever know who of what 'god' is, or isn't? So to speak of "probabilities" is silly.

I don't agree with your definition of agnostic, since I believe the word agnostic means a BELIEF that the existence of god/s is an UNKNOWN. Because of my understanding of the word, I don't register on your 0.01 - 99.99% spectrum.

I have 0 belief that gods exist, and I believe that there is 0 possibility to KNOW whether god/s exist or not. I say that because I'm, um, agnostic.

There's no percentage of belief or probability I can report that god/s exist.

To me, a god is something that can't be known, only believed in. That's my take on it.

Wtf are you dragging up the Atheist Agnostic tempest in a teapot ?? Atheists are rational evaluating religions demanding evidence for their allegations..... my Agnostic comrades are conforming to the false Webster definition of Atheism fearing to fall into that trap of disproving a negative..... your absurd rambling here about percentages is far worse than deluded bigots of the Noah Webster successor publishers.... for example they equate Deism with Atheism due to their loyalty to xian dogma geebush geehobah ghostholes.....calling Thomas Paine a : " filthy little Atheist " quoting Teddy Roosevelt..... to stir up trouble AGAIN especially between new members here fresh out of the cults MUDDLES OUR COMMUNITY and our very name AGNOSTIC DOT COM

What’s a god?

Given that nobody has ever provided any falsifiable evidence to support the existence claim of any god, it is not possible to assign a probably to the existence of any such god.

To assign such a probability is to commit a classification fallacy.

Anybody who claims that any god either exists or probably exists is being absurd.

I can not say, for sure, that I exist. I will venture no odds for such a concept. If I do exist then Zen says I’m God.
