> Any "naturalistic first cause" at this point is mere speculation without foundation.
Well, the thing about a naturalistic first cause is that it doesn't make the assumptions that the theistic first cause makes. It's true that there are many unknowns, but the key difference is intelligence (and whether it's personal, I suppose.) We don't really make any other claims about it, because we can't know, but in a similar fashion there are many things that theists claim are unknown about God, as well - either we can't know (he's beyond human comprehension) or we just don't know (God acts in mysterious ways). Again, I think the key difference, (and therefore, what should be the focus of the argument) is whether the FC is personal and/or intelligent.
Let's not worry about any of the above, though. I think we're largely on the same page. Just as a thought experiment, which of the following would you agree with?
1. If the FC is not intelligent, then it is not God.
2. If the FC is not personal, then it is not God.
3. If the FC is neither intelligent nor personal, then it is not God.
4. If the FC is intelligent, then it is God.
5. If the FC is personal, then it is God.
6. If the FC is both intelligent and personal, then it is God.
I would agree with 1, 3, 4, 6, and maybe 2 and 5. This depends on how my understanding of your concept of personality changes.
Personality
Let me share with you a bit of my understanding of the universe. Disclaimer: As far as I am aware, this is a very scientific understanding, but I am combining quantum physics with philosophy, which is a very touchy subject combination. Therefore, you will find very few scientists who necessarily agree with me, since most scientists are not quantum physicists, and many quantum physicists are not also philosophers. I myself am also very uneducated in regards to quantum physics, but I think the specifics are not actually too important. However, I am more educated than the average person (albeit not by much) in terms of Artificial Intelligence, so I have a pretty specific understanding of the problem of consciousness. So, here's my understanding.
Fundamental particles:
I'm sure you know that quantum physics is weird. No one really knows how or why particles interact at their most basic levels. Quantum physics, though, is about particle and field interactions. There are, in theory, just a couple basic particles and rules. In fact, it could be (and in fact is very likely to be) just one kind of fundamental particle with one rule - e.g. a particle with a directional magnetic field. Probably not that, but something that's at least comparable.*
So, you have the entire universe composed of that one, single particle, and, in the beginning (before time, space, matter, etc. existed), maybe it was entirely, perfectly, ordered. Maybe there was chaos. And that's all the universe was. Then, something happened.** This was the First Cause (FC).
Chaos:
So, the FC caused something like this (https://conversationofmomentum.files.wo ... &h=&crop=1). A stable, ordered system with no motion was thrown into chaos by one little disturbance.
Another good gif is this one (https://www.reddit.com/r/dataisbeautifu ... h=04a8f60a). Two particles together with two simple rules (they maintain the same distance, and are pulled in the direction of gravity) produce an immense amount of chaos - almost completely unpredictable (but not truly random), with a huge amount of information within.
So, simple rules cause a chaotic universe. Although it appears randomized (and therefore non-deterministic), it is actually completely determined by its few basic rules and was thrown into chaos by one tiny event.
Order:
When there's chaos between interacting deterministic particles, they form certain patterns. Galaxies, for example, are formed by planets and stars. Planets and stars are formed by dust. Dust is formed from atoms and molecules. Atoms and molecules are formed by protons, electrons, and neutrons. This probably goes several levels deep. Any chaotic simulation will give similar results, and you don't need random variables (although subatomic particles are difficult to simulate, because we don't know all of their properties and rules.)
With enough chaotic particles forming small patterns, you can form more and more complex patterns. Electrons/protons/neutrons form different elements. Different elements form different molecules. Different molecules form crystalline structures, liquids/gases/solids, planets, rocks, etc. With enough particles (and we have an inconceivable number in our universe) you can create incredible complex structures (with enough snowflakes, you'll eventually make every one.) Eventually, you might create one that can self-replicate (life). This is testable in Conway's Game of Life, although not on the level that we have in our own universe.
Life:
All that's required for life is self-replication and mutation. From there, the most viable forms survive and evolution begins. More and more complex structures evolve as they compete for resources in a never-ending arms race, and eventually you get intelligent life. From an evolutionary standpoint, you see, intelligence is rare, but it isn't necessarily anything mystical. It's just another means to survive. It's how humans came to be on the top of the food chain.
See, humans don't just pop into existence - we're too complex. Neither do molecules. Molecules formed from something smaller, and more fundamental. Complex structures beget more complex structures.***
Personality:
I think this is important here, because I feel like you're referring to consciousness when you say "personal". You've definitely referred to:
1. Consciousness
2. Truth
3. Catsup
4. Subject/object differentiation
But I feel like these are all human concepts. If we were evolved from chaos, not deliberately created, then we're just bundles of fundamental particles that managed to come together in a "thinking" pattern. The universe doesn't care about us, we're just new types of "particles" the same way a planet is a "particle" or an atom is a "particle". Sure, we are more complex, but in general, complexity begets more complexity. But the universe doesn't care about the distinction between catsup and a rock, they're just bundles of atoms in different patterns - just like the difference between a human and a rock. "Truth" is a construct of the human mind, as is any objective morality, or even language. Can you possibly show otherwise?
Intelligence:
So what's special about intelligence, or consciousness, or "personality"? What question needs to be answered? Sure, if there's something special about life, if a "soul" is a type of fundamental particle, maybe there's a personal God that made it that way. But there's nothing that says that there is.
You should look up some short videos about neural networks if you're not familiar. We've created minds that can think and reason, to a certain extent, and we know a lot about how they work. We haven't created one as complex as a human mind, but we're getting surprisingly close. If this interests you at all, watch the AlphaGo documentary on Netflix. That artificial mind is capable of creating strategies to the board game Go that human experts would never have thought of - it's smarter than we are.
Sure, we can't replicate emotion, language, or visual processing yet, but there's no evidence that those concepts are different than regular data processing, except in terms of complexity. I strongly believe we'll get there sooner than you'd think - possibly the next couple decades.
A side note about information:
Information is "facts provided or learned about something or someone" or "what is conveyed or represented by a particular arrangement or sequence of things".
A particle itself is not information. Information refers to writing, bits, sound, etc. All of this has information coded within, that conveys an idea about something else. "Information" is another human construct, just like truth, morals, and love are human constructs. It's likely that you're referring to something else when you refer to "informational data", and I think that that something else is patterns and sequences. Patterns and sequences are absolutely something that occurs naturally. Planets and their orbits occur naturally. Crystalline structures occur naturally. Molecules occur naturally, formed from atoms, and they have plenty of sequential patterns. DNA occurs naturally (although admittedly, it's usually created by other DNA - that's how complexity begets more complexity.) DNA is just another sequential pattern with a mixture of chaos and order, but it's one that happens to be particularly complex.
*I'm using this as an example. Maybe there are two fundamental particles, I don't have any way to know. The logical scientific consensus seems to be that it's just a couple simple particles/fields/rules - we've imagined fundamental particles (the atom) even before we could see cells or molecules.
**If the universe was chaotic, I would say it's more likely that these FCs happen all the time, and there are trillions of universes. Still, though, my little essay here is just explaining our own universe.
***I think this is important, because you bring up the "question of complexity". I don't think there is a question. We know that complex creatures create more complex creatures, and chaos breeds more chaos. It's natural to the universe. Complexity is not a constant that can be neither created nor destroyed - rather, it necessarily adds to itself.
