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?
First of all, there are very very few things I would consider 100% certainty about.
As for god(s), I doubt their existence about as much as I doubt the existence of ghosts and magic (actual magic, like harry potter style magic; not david copper field style magic).
In percentage, I would say it's about 99%, if not higher, but certainly not 100.
Note that when I speak of god(s), I'm referring to god concepts that I have been presented with (in literature or by people in person).
Supernatural entities that "do" things.
As for what I base that one.... I base it on many different independent lines of evidence.
In random order a few examples:
- many times things are attributed to gods, they turn out to be no more then arguments from ignorance, special pleading, etc
- zero independently verifiable evidence for any god
- every time science and religion go head to head to explain some phenomenon, either science wins or the question is left unanswered. Never does religion win
- human psychology (tendency to engage in superstition; tendency to engage in type 2 cognition errors etc)
- direct observation of religions / gods being invented (rastafarianism, scientology, that religion on that remote island where they think prince (now king) charles is god, etc)
- the many many many many phenomenon around which entire religions were build which today have common natural explanations
- ....
From whatever angle I look at it, god beliefs always look / smell / feel like sheer superstition.
For all practical intents and purposes, we can live our lives assuming gods fall in the same category as ghosts, leprechauns, extra-dimensional unicorns,.....
Things with no detectable manifestation whatsoever are irrelevant and look exactly like non-existent things.
So I could also say that even IF gods exists - they matter not.
