Why can't you prove godlessness? Because it is impossible to prove the denial of the existence of Jesus Christ.
Nor is it necessary for atheism.
atheism cannot be proven.
Atheism isn't a claim about gods or reality beyond a statement of personal unbelief. It is an opinion based in skepticism and empiricism, and in its agnostic form, cannot be right or wrong. I don't believe in any gods. That cannot be wrong unless I am lying about my opinion.
So atheism is anti-scientific.
Agnostic atheism is the only possible sound position for an empiricist. Absent sufficient evidence to believe, he doesn't. Absent sufficient evidence to falsify the claim, which of course is always the case with unfalsifiable claims, he doesn't deny the possibility. I've ruled out the possibility of tri-omni interventionist gods, but I have no observation, argument, experiment, or algorithm that can exclude say the deist god. Nor is that an issue, since the existence or nonexistence of noninterventional gods would be irrelevant (
apatheism).
I am speaking about GNOSTIC ATHEISM only. The other atheisms are ill-defined.
To you perhaps. Theists have a difficult time with the nomenclature most atheists are using today. I still see a few say that they are more agnostic than atheist, which represents the nomenclature of the past created by theists, but most know what other people self-identifying as atheists are saying when they use the word, and it seems many if not most theists in these threads either can't understand the difference between lack of belief (I call this unbelief) and disbelief, or resist trying to.
For this type of atheist using this nomenclature, there all atheist have in common a lack of belief in gods. One can then subdivide them a few ways - gnostic versus agnostic, humanist or other (Stalinist or any other worldview lacking gods that is not humanist), apatheist or not, antitheist or not, etc..
Atheism is the denial of any supernatural form of existence, including any gods, despite so many atheists constantly insisting otherwise.
Here's another atheist telling you that that is your definition, not his. You're one who refuses to countenance the distinction between unbelief and disbelief. I'm an atheist, and I just finished explaining why I don't assert that gods don't exist. I'm sure you'll continue to make this error for years to come, and you can expect some atheist to correct you when you do.
I say this because "dis-belief" is not the same as being undecided.
Correct. We have both types of atheist, and they differ by one belief.
Humans have no means, physical or otherwise, by which we could determine the existence of any sort of god simply because our concept of God places it outside and beyond the reach of existence as we know it.
That is true of every fictional creature and space. That is the very definition of nonexistent - not found interacting with reality, not detectable even in principle anywhere any time. Everything that exists can be found somewhere, sometime, somehow if one is in the right time and place and has the proper detector, which might be the unaided senses or devices to supplement them. All three of these are true for whatever is real, and none is true for fictional entities. There is nothing for which one or two of these things is true. All three in the real, none in the fictional.
Let me illustrate. Let's compare wolves to werewolves, one real, one imagined. Because wolves exist, there are times and places where one can detect and interact with one. Because werewolves don't exist, none of those is possible. When you describe a deity as existing outside of time and space and being necessarily undetectable to us (cf. contingently undetectable), you are also describing werewolves. And vampires, leprechauns, succubi, fairies, Santa Clause, and Superman. They all have the same properties - none - and share the same ontological status.
In fact, we can't even comprehend how anything could lay beyond it. It's logically incoherent.
Yes, the concept of the supernatural is incoherent. That's generally a reason to reject an idea. The idea that something exists outside of time is incoherent, as
@Ella S. suggested with her reference to causality. To claim that something that can modify nature but is not another aspect of nature is incoherent. To say that there is a realm that is causally connected to nature and can modify it but is undetectable is incoherent. When you say that something can affect us but is necessarily undetectable, that is incoherent, since we can detect those effects.
