> I think you are equivocating between the laws that govern material interaction and things that interact with matter. They are not the same thing. The laws of physics are developed by breaking matter down to its most uniform and granular components, and then characterizing their interaction. An immaterial soul would not be captured by such an analysis, but its interaction with matter could still be empirically identified.
If an "immaterial soul" interacted with matter in an empirically identifiable way, it is part of physics. The forces that interact with matter are themselves not made out of matter. To be precise, matter is only that which has a mass, but there are also particles that don't have mass. Their interactions are nevertheless part of physics and we can measure them at least indirectly. They're not abstract constructs, they're very much part of the physical universe.
In that sense, perhaps the term "materialism" is misleading, because ultimately physics is about forces, not matter. Remember, I'm not using that term for myself.
> However, if there are only a few specific, long coin sequence you are trying to construct, then flipping a coin does not get you there. There are just too many possibilities within a couple hundred coin flips to check within the lifespan of the universe.
There isn't just a single coin though. There's about 10^46 molecules in the ocean[1]. That's a lot of interactions over the span of billions of years.
> And, if you have one of these sequences, then randomly flipping some of the coins will destroy the sequence. Just think about what happens if you flip random bits in a computer program. For the most part, unless you get really, really lucky, it will destroy the computer program.
It depends on the bits flipped. Bits flip all the time[2] and people rarely notice, because they're not necessarily important bits. It also depends on whether the program will abort upon error detection. Without memory protection by the operating system, most programs wouldn't terminate, they'd keep trucking along, perhaps producing some garbage here and there. In fact, the difficult part about memory corruption bugs is that the program often won't terminate until well after the corruption has taken place.
Also, computer programs aren't like organisms exposed to nature. In nature, it's possible that a mutation kills you, but it's far more likely that some physical process or another organism kills you.
> So, while a few random mutations may be very lucky and flip the right nucleotides to create new functionality, the vast majority of mutations are destructive, and will kill off the species before there is the chance to evolve new functionality.
The vast majority of mutations are relatively inconsequential, at least for short-term survival. Our DNA mutates all the time, but also we have evolved error correction, which you probably also will not accept as evolving "by random mutation and selection".

You seem to want to call every interacting thing 'physics', which you are free to do, but then I'm not sure what the value of the term is. And, you agree we already empirically measure many immaterial things. So you seem to agree that in theory an immaterial soul is an empirically testable hypothesis, in which case I'm not sure what your objection is. As for the number of interactions, we have trouble reasoning about large numbers. Billions of years and molecules sound like unimaginably large numbers and of similar magnitude to trillions or decillion, even though the latter are many orders of magnitude greater. DNA sequences can be hundreds of billions of base pairs long. So, if we could only depend on random mutation and natural selection, we'd need 4^10^11 attempts to hit a particular sequence, which is more trials than even a multiverse of universes can offer.

You seem to want to call every interacting thing 'physics', which you are free to do, but then I'm not sure what the value of the term is. Everything that interacts with matter is in the domain of physics. So if your concept of a "soul" (or whatever makes you a "dualist") can at least in principle be observed, we can count it in. It's then not "beyond this universe". It would also raise a lot of questions: Are souls "individuals"? If so, does every organism afford a soul? If so, where do new souls come from when the amount of organisms increases? Where do they go if they decrease? Is there really only one soul spanning all organisms? How can we test for any of these things? What are the consequences? It's perfectly fine to explore such questions, but I am personally not convinced that something like a soul - within or outside the realms of physics - is at all necessary to explain life or intelligence as the phenomena we can already observe. That's what we disagree on. > DNA sequences can be hundreds of billions of base pairs long. Perhaps, but the simplest lifeforms alive today have on the order of hundreds of thousands of base pairs. > So, if we could only depend on random mutation and natural selection, we'd need 4^10^11 attempts to hit a particular sequence, which is more trials than even a multiverse of universes can offer. Yes, but DNA didn't just form spontaneously, fully assembled. It formed from simpler precursors, which formed from simpler precursors still, all the way down to proteins which formed from the simplest of molecules. Those precursors don't survive because they can not compete with their successors. They could be forming in the oceans right now, but they won't progress because they'll just get eaten. There have been experiments done reproducing it up to the "protein formation" step. Anything more complex than that is likely going to take too much time to result in a new lifeform - especially one that could survive ex-vitro.
