At this point, I have to admit I don't understand what it is you are trying to understand.
Hypocrisy. The hypocrisy of saying; "I don't accept the theist claim that gods exist because theists can't prove their claim to be true using the evidence and logic that I demand. But I do accept atheist claim that no gods exist even though I cannot prove it to be so using the same evidence and logic that I demanded of theism."
And then when they these hypocrites are asked to explain this hypocrisy, they say; "even though I am calling myself an atheist, and I believe no gods exist, I am not making the atheist claim, so I don't have to defend it." So, ... even more hypocrisy in defense of the original hypocrisy.
And when I try to point this hypocrisy out, they just keep saying over and over and over that they aren't really atheists but they can call themselves atheists because they decided the word atheism doesn't mean atheism, it means whatever they say it means, but not that no gods exist except when someone else says it.
I thought you wanted to know why an atheist would want to deny god beliefs when an atheist would also claim to not being able to know all there is to know about all existence.
Denying someone else's belief is an empty absurdity. No one cares, because it's meaningless in and of itself. If one rejects the theist assertion that gods exist, one can do so on only two possible grounds: one lacks sufficient information to determine whether gods exist or not, or one accepts the counter-assertion that no gods exist. That's it. There are no other logical possibilities. So if one claims to lack sufficient information to determine whether gods exist or not, how can they logically then counter claim that no gods exist? And if they counter claim that no gods exist, how can they logically claim that they lacked sufficient information to make the determination? They either made the determination or they didn't. And if they made the determination, and they lack sufficient information, then upon what reasoning did they make their determination?
My only answer is that I no longer believe stories about gods because I understand why humans hold beliefs in gods. It is no longer possible to believe in them as something outside of human imagination, wishful thinking and desire to have an all powerful friend and caregiver always there no matter what horrible thing real life may bring.
None of this is about anyone's "stories about gods". Rejecting stories about gods is only rejecting religious depictions of the gods, it's not rejecting the existence of any gods. Being against religious depictions of gods does not make anyone an atheist. Plenty of theists also reject religious depictions of gods.
There is just no evidence of any kind, anywhere that would point to a place in space for gods to exist or interact with humans.
But the "evidence" you were looking for was being determined for you by religious depictions of the gods that you have already rejected. So what ACTUAL evidence for the existence of God/gods are you expecting to be able to find, if such gods exist? I mean, if you don't know what evidence should be expected, how can you know whether or not you've found it?
It is just implausible. Can you actually look at the stary night sky and say to yourself that a God did it? If so why? What would lead you to believe that a God created it? What would be the point of a god creating the universe and then not interacting with the supposed creatures it created in any physical way? The only way to discern and be one with this creature is through unquestionable faith and prayer?
Are you claiming that because you can't understand the existence of any gods, they must not exist? Because that would be an argument from ignorance. Which is traditionally considered an illogical argument.
No, it just doesn't work that way for some people. If it doesn't make sense or experience can be explained better by nature, the unverifiable and wishful ideas of the supernatural are likely not true. So I don't believe the claims.
What makes you presume that as a mere human, you should be able to understand and verify the nature and existence of the gods? I fail to see how you think you would be able to do that. I know I would not be able to do that, even if "God" were hovering in a blaze of glory, right in front of me. I still would be able to determine, logically, that it really was God, as opposed to some mental aberration, or some clever magic trick, or some advanced alien species, or simply something else that I am as yet unaware of. So if I cannot even validate such apparent evidence, how could I possibly validate the less obvious or abstract evidence that my fellow humans are offering?
It seems clear enough to me why humans desire gods. There is no doubt that many humans need to believe in a higher power. However, just because there is a need for and satisfaction from believing, does not make the beliefs real.
"Real" compared to what? Why aren't our needs considered "real" to you? Why aren't those needs being met even more real to you? They certainly seem to be real to me, and to pretty much every human being, everywhere. I mean we are all living our lives in response to those needs, and in pursuit of meeting them. So what makes these particular needs "unreal" compared to the ones you consider "real"?
For the atheist, what matters is what is known about gods and not beliefs about what maybe real about gods.
What is known about gods that isn't just "belief"? And if the answer is that nothing is known, then why are they atheists?
