Is there any room in your belief to doubt God exists?
Or do you believe in God with 100% certainty?
If you're agnostic does that mean you believe there is a 50% chance God exists and a 50% chance he doesn't?
If you don't believe in God or gods are you 100% certain there is no God(s)? 90%, 70%?
If you believe in more than one God are there some gods you don't believe in? How certain that these gods you don't believe in don't exist?
What do you base this percentage of non-belief on?
I don't see it as a matter of measuring percentage of belief or certainty. I don't know of any "gods" that exist, and any speculation I might make in that regard would be mere guessing and imagining.
I'm fairly certain that I exist, and that being the case, it stands to reason that "something" exists, but what that "something" might be, I have no idea. I don't how that can translate into a percentage of certainty of "god exists" or "no god exists." I tend to identify as agnostic myself, although I don't see it as a kind of 50/50 proposition.
If we define "God" as "the thing which set the universe in motion which led to the natural development of solar systems and planets and the evolution of 'life' as we know it," then I would say that I don't know what that "thing" is. The universe exists, and there are objects in motion.
It seems to me the matter of contention is not "if" there is "something" that set the universe in motion, but what that "something" happens to be.
There are those who skip over that part and assume that it must be "someone" who set the universe in motion, without first knowing what "thing" it is first. It's all such a mystery, but "god" is often used as a placeholder for the mysteries of the universe we don't know. Others might become more specific about it and ascribe human attributes to their god or gods, such as love, jealousy, revenge, rage, etc. Some people believe in different gods or might have different conceptions about the universe and the origins of life. Some see it as some kind of grand design or divine plan for something, where even the minutest details of an individual's life "happen for a reason." But it's all based on some assumption that "someone" must have caused all of this intentionally.
