..and that includes disbelief in God..
Disbelief, is not a belief.
I see that lots of people believe in the Bible and Qur'an, and I also see
that there is a good reason to believe.
I see no good reasons to believe. And whenever people give me their reasons to believe, I see that they aren't good reasons.
You prefer to "err" on the side of caution, and think that there is probably no creator .. none superior,
and that this life is all there is .. da da .. da da..
Not quite sure what you are saying, but it seems you are making the classic mistake of misrepresenting what atheism is.
Theism is the claim.
I am unconvinced of said claim. That, and only that, makes me an atheist.
For all
practical intents and purposes that means I go through life
as if the claim is false, yes. But that is out of necessity, not out of conviction.
I don't make the claim that there are no gods. I don't lose any sleep over that nor do I consider it a meaningful claim.
Consider an analogy...
Let's say that we are in a car on a high way.
You claim that up ahead, a pile of invisible rocks is blocking my way.
I don't believe your claim. I'm not claiming there is no such pile of rocks. I just don't believe your claim that there is.
Due to this disbelief, I will not bother changing lanes or slamming my breaks. I will just drive on
as if there is no such pile of rocks.
This is, again, out of practical necessity.
Or consider the analogy of the court case.
A defendant is either guilty OR innocent. But only the claim of guilt is discussed.
When the defendant "wins" the case, he is NOT ruled "innocent". He is instead ruled "not guilty".
And as a result, he is set free. So out of practical necessity, the defendant is treated
as if he is innocent (not guilty).
But he is not ruled innocent. The case wasn't about determining that. It is about determining guilt.
The defendant is
considered innocent
until shown guilty.
So as an atheist, you could say that I rule god to be "not guilty" of existing.
