How can you claim both that there is valid evidence and that we can't clarify and validate that to which this evidence is supposed to point?
I said "legitimate" evidence. All evdence is legimate, but not all evidence can be validated. For us to validate evidence for the nature or existence of God would require that we be able to reasonably define and contain the nature and existence of God. But our general definition of God is so encompassing that all evidence could be reasoned to be valid or invalid. And we have no way around this.
If you don't know what you are looking for, how can you know where to look, let alone know if you have found it?
Exactly. Which is why we have never been able to resolve this conundrum. It's not a lack of evidence. It's a lack of specificity. And we simply do not have the capability for resolving that problem.
All reasonable ideas. But to me they all lead to either "we don't know" or the somewhat stronger "we can't know".
That is where we are if we are being honest and reasonable. Yes. Everything else is just belief/opinion/guessing whether we know it and admit it, or not.
I'm drawing this conclusion from your words here. Then you go on to claim that you have legitimate evidence for something or other that is just a collection of words if we can't "clarify and validate" what they purport to relate to.
All evidence is legitimate.
Too many people these days have adopted the foolish notion that evidence is defined by it's ability to convince them of something. This is false. Evidence is evidence whether they are convinced buy it or not. There is ALWAYS evidence. Just the fact of the question "does God exist" is evidence that God exists. (It could also be used as evidence that God does ot exist.) You do not have to be convinced by it for it to be evidence.
I'm perfectly OK with your basic conclusions, in fact it seems perfectly reasonable that something so different from us that a god might be would be beyond our understanding. But having said that, you have to stop there in making claims about it.
No one is actually making any claims, ... not if they are being honest and reasonable about it. The only people making actual claims are people that have falsely convinced themselves that they know the answer to a question that no one can know the answer to (without reasonable doubt).
If God appeared right in front of you, in whatever blaze of glory that would entail, how would you verify that it was God, as opposed to some very clever magician's trick, or some anomaly within your own mind, or even some advanced alien visiting you in a form that it thinks you would be able to understand? And even if you were somehow able to determine that it is one of these other circumstances, how could you be certain that these other circumstances didn't enable a real experience of God?
The answer is that none of us could possibly verify even a direct physical experience of God, as an actual 'real' experience of God. It cannot honestly or reasonably be done. And that fact that is also legitimate "evidence" ... for which conclusion is up to you.
