Is it not the result of flawless logic to conclude that self-replicating code cannot self-originate?
As you've presented it, it's an unevidenced claim. You'll need to add a sound, evidenced argument to convince here.
Nonexistent. And we can assign criteria to define the two. Real and actual refer to the collection of objects and processes existing in space and time that can affect one another. This is nature. Ideas may be real (exist in heads in spacetime and manifest as actions), but their referents need not be, in which case we call the referent imaginary or unreal, since it can be found nowhere and causes nothing. This definition includes all of existence including any reality outside of the bubble of spacetime we call our universe yet causally connected to it.
If it happens to be embedded in a multiverse from which it arose, that, too, is real, exists in a meta-spacetime in which our T=0 was a moment in its timeframe, much like we arise on our birthdays, our personal T=0, but we get a date for that from a meta-timeline that goes on the birth certificate as a date of birth.
If there happens to be a god, it too exists in a spaciotemporal reference, and is also part of nature.
To frame it any other way is to be adrift in incoherent thoughts and claims such as the supernatural or gods existing outside of time - internally contradictory concepts.
We outside can conceive of causally disconnected realities outside of what I am calling nature here, but such thoughts are sterile, and such "realities" can be treated as nonexistent and never thought of again. Claims about them are unfalsifiable and this "not even wrong."
So, if there is more than our island of interconnected objects and processes, we disregard it. Nature and reality are those things that can impact one another.
unless God is the origin of "nature", and therefor precedes/transcends it.
That's an incoherent thought in the framework I've offered. If a god exists, it's part of nature as well and subject to laws of nature that pertain to that higher order meta-spacetime. What keeps this deity intact? Why doesn't all of its knowledge become corrupted? Why doesn't it dissipate away like a cloud? Something prevents that.
The fine-tuning argument for gods implies that. If a god has to discover the laws of nature and manipulate them to create a universe finely tuned for life, what does it say about the omnipotence of that deity or its relationship to nature?
I've never understood the weird insistence that God must be physically extant or not at all.
See above. If you consider that framework flawed, demonstrate the error if you can or just accept that you simply don't like it for reasons you can't state.
Lots of things are not physically extant and yet are as "real" to us as anything that is.
Disagree. And there you go with those quotes. If your metaphysics is tethered to nothing but your imagination, and if your definitions are so fuzzy that real becomes "real" for you, you have no foundation for a self-consistent view of reality. It's possible the framework I presented needs tweaking, but not until observations arise that contradict it. As long as it serves as an adequate scaffolding for understanding experience, it's a valid perspective.
As
@blü 2 implied, we need a clear idea of what we mean when we use words to think effectively. Words perforce have a degree of fuzziness, but we can minimize that and owe it to ourselves to do so, because the alternative is freeform thought (creativity), which is great for generating hypotheses for testing and for other creative purposes such as the arts, but not for adding beliefs to one's fund of knowledge, nor for navigating life.
This is irrelevant nonsense, of course, meant to discredit and insult, not illuminate.
He wrote, "In that context the unicorn is light years ahead ─ at least we know what we're looking for and if we found an equine with a single horn on its forehead and probably white hair, and if we had a virgin female handy, then we'd know."
I see this every time a god is compared to anything else - "I'm offended that you equate my unevidenced belief with other unevidenced beliefs like unicorns." What would be an inoffensive analogy for you? Or is this entire area off limits for you?
