Not guilty and innocent are different to exists/does not exist though.
I disagree.
God exists = Gotti is guilty
God does not exist = Gotti is innocent.
These are two different propositions. And only one outcome is mutually exclusive (= where you believe both).
You can not believe both.
You can believe the first and not the second.
You can believe the second and not the first.
You can disbelieve both.
You can't believe both (that would be self-contradictory).
The theist / atheist debate is essentially about the first proposition only.
As an atheist, I rule god "not guilty" of existing.
Yes, and thus there is no practical difference as, for you, that truck does not exist.
For practical intents and purposes, there isn't, indeed. But the debate here isn't about practical intents and purposes. It's about convictions and beliefs.
If someone asks me "Is there an invisible truck that is about to kill you?" I believe that there is not because there is no reason to believe there is.
Consider the bolded part.
Now consider the opposite question.
"Is there no invisible truck that is about the kill you?"
Would you consider it valid to reply "I believe there is
because there is no reason to believe there is not"?
Likely, you will not.
This is so because the negative version is a valueless claim. It's the positive claim of existence that is the subject of discussion.
Nobody goes to court to sue for innocense.
We discuss guilt (existince).
We don't discuss innocense (non-existence).
Off course, if you CAN demonstrate / prove innocense / non-existence, all the more power to you. But you'll still be doing it in
response to a claim of guilt / existence.
Someone needs to claim the existence of a god before we will even contemplate that god's non-existence. Atheism (both weak and strong, in fact) thus is a reactive position. Not a stand alone assertion by itself. As a stand alone assertion by itself, it is entirely meaningless.
It would be like me completely out of the blue starting a thread to demonstrate that I did NOT rape Cameron Diaz last night.
Why would I bother, if nobody accused me of doing that?
