First you repeat the claim that fine tuning does not commit you to a religion, and then you keep appealing to religion all the way throughout. That's self-refutation at its finest.

You can stop saying "any particular religion" and just say "religion." I do accept that although fine tuning is almost exclusively pushed by Christian quacks, other religions can push it too. It also seems to be a bit of a straw-man, as I never asserted that it commits you to a specific religion, or to religion for that matter. You inevitably have to come back to it, as there is nowhere else you can take this nonsense, as you have aptly demonstrated, but you don't have to "commit" to it at the onset.

Then you comically bring up Spinoza, seemingly to strengthen your "any particular religion" point, but perhaps without realizing that he undermines your "understanding the designer" point. And you acknowledge literally in the same paragraph that he might have been an atheist. And not only that, but his concept of God, such as it is, is totally incompatible with fine tuning, because he doesn't even ascribe it intelligence. And not just that, but Spinoza ascribes quite meager power to the human mind, even denying us free will. So much for "understanding the designer" with Spinoza. Another self-refutation.

Then you even more comically bring up Aristotle, claiming that he has "no affiliation with any traditional religion," perhaps without realizing that Aristotle has become a staple in Christian theology from St. Aquinas onward. And not just that, but Aristotle also thought that God was beyond human comprehension. Another self-refutation.

Then you repeat your point about the problem of evil, without adding anything new, although it's already been refuted. The problem of evil does not help you come to understand something about the designer. All it does is weaken the ontological argument, and other arguments that depend on benevolence, and brings into question free will in both the designer and the human mind, without moving the needle one bit on any of the other issues that you have to content with in a benevolent designer.

Then you concede that fine tuning does indeed move us out of science, when earlier you were trying to demonstrate that it doesn't by citing the Elon Musk simulation joke meme. Nice.

I appreciate you clarifying the language on "understanding." Of course there is no such thing as scientific understanding of the designer, as science doesn't even recognize the concept (thank God, pun intended.) I thought you were the one trying to stay within science because you kept saying that you don't have to commit to religion, and citing things like the simulation hypothesis. When I say that the designer is beyond understanding, I mean primarily in the religious and metaphysical sense. In religion, his ways are mysterious. In metaphysics, he is all-knowing while the human mind is constrained and limited to our senses. That said, I would have accepted it if you were able to somehow demonstrate that there can be a scientific understanding of this concept, but it's now clear that that's not happening.

Also when I say "understanding" I obviously don't mean ascribing it paradoxical and otherwise nonsensical attributes the way I can assert right now that it has three eyes and a four-sided triangle for a mouth. When I say "understanding" I mean understanding why and what this designer is, as you put it earlier. I mean understanding how it came to be this way; to be able to go around fine-tuning things?

In your last paragraph you seem to want to broaden the scope of the dialogue without having refuted or conceded the point on understanding the designer, but we're going to have to stick to that until it's resolved, because it's kinda important. So here is the simple assertion you need to either refute or concede:

"Fine tuning posits a designer that is beyond human capacity to understand."
