Hi ecco
Now I am going to play with words, but not as religious. I am something else also, I am a skeptic. So I am going to play with the word "knowledge". And I am going to use reducitio ad absurdum in the end.
I will take the following for granted. I am not everything(solipsism), rather I am caused by something else, the rest of everything, but it is not ontological dualism, since I am a part of everything.
So now it is science time, methodological naturalism and how it is that we don't have know what ultimate reality is. I need QM and a Boltzmann Brain. Since you use wiki, I will do that:
The
Boltzmann brain argument suggests that it is more likely for a single brain to spontaneously and briefly form in a void (complete with a false memory of having existed in our universe) than it is for our universe to have come about in the way modern science thinks it actually did. It is a
reductio ad absurdum response to
Ludwig Boltzmann's early explanation for the low-entropy state of our universe

Now that is insufficient to understand the problem of how to determine the likelihood of you being a Boltzmann Brain. Here is how it is unknown what reality is outside your experience of it.
Reality is, as it appears to you, caused by something else, than your experience of it. I.e. objective reality independent of your mind. But if reality is not as it appears to you, you still only have your experience of it. So knowledge is the belief and faith in that reality independent of you, is as it appears to you.
This is not limited to a Boltzmann Brain, it is a problem of grounding knowledge about reality independent of the mind. Nobody in the recorded history of mankind have solved that and it is connected to this problem in regards to knowledge.
- Dissent – The uncertainty demonstrated by the differences of opinions among philosophers and people in general.
- Progress ad infinitum – All proof rests on matters themselves in need of proof, and so on to infinity.
- Relation – All things are changed as their relations become changed, or, as we look upon them from different points of view.
- Assumption – The truth asserted is based on an unsupported assumption.
- Circularity – The truth asserted involves a circularity of proofs.

This is not about truth per se, but rather about the limit of proof, evidence, reason and logic and indeed knowledge.
It ends here with the apparent reality that we are both a part of. It is as much a fact that you understand reality differently than a religious person, as it is a fact that a religious person understand reality differently than you, yet you are both a part of reality. No matter how much another person's thinking is nonsense to you, that is also so in the other direction. That is Aristotle and the psychology of logic. You can't believe something you don't believe as that is a contradiction, but that doesn't stop other humans from believing differently. That also works in the other direction.
So here it is as nonsense in regards to science:
Science has limits: A few things that science does not do
Science doesn't make moral judgments
Science doesn't make aesthetic judgments
Science doesn't tell you how to use scientific knowledge
Science doesn't draw conclusions about supernatural explanations
Science is the assumption that reality is as it appear to humans, but no evidence, proof, reason, logic or what ever can be given for that. Indeed within reality as it appears atheism and religion are both natural human behavior and that is that. If you want to claim that religion is nonsense, then don't use science for that. You can't because nonsense is a process in your brain and not a result of observation. You can't see what makes sense or not, so you are not doing science. You are doing philosophy, psychology, politics or what ever. I know that and I also know that about myself. I know that science has limits. I use science for reality as it appears and religion to make sense of reality. And yes, that is not how you do it, but I don't care, because it works for me. And I accept that you do it differently for yourself, but I don't accept that you claim authority about what is nonsense not just for you, but for all humans including me and other religious humans. I go reductio ad absurdum on your claim of knowledge of what ultimate reality is. You don't know that, nor do I. I know that and you believe differently.
So here it is for knowledge about that which is independent of the mind, other than it is independent of the mind. It is nonsense to claim such knowledge, because knowledge happens in the mind and if it is independent of the mind, it is unknown. All forms of strong knowledge of what reality really is, is not knowledge, but beliefs. I know that, since I am a skeptic.
