You're making several claims here that don't actually establish what you think they establish. First, the first law of thermodynamics does NOT say that matter and energy are "eternal" or that they must have existed forever. It says, roughly, that energy is conserved within the applicable physical framework. That's very different from saying: "Physical reality necessarily exists and has existed for an infinite amount of time." Those are completely different claims. In fact, modern cosmology treats spacetime itself as dynamical, and the usual conservation equations are formulated within particular physical models. The philosophical literature on cosmology explicitly distinguishes physical conservation laws from the much larger metaphysical question of why there is a physical universe at all. So your argument: matter/energy is conserved → therefore matter/energy is eternal → therefore God isn't necessary doesn't follow. You're smuggling "eternal" and "necessary" into a law that doesn't establish either. Even if matter-energy has existed eternally, my argument survives, because I wasn't arguing that the universe needs God merely because it had a first moment. I'm asking why contingent physical reality exists at all. An eternal thing can still be contingent. Something can exist at every time without existing necessarily. "It has no beginning" does not logically entail "it could not have failed to exist." So you haven't actually answered the contingency argument—you've answered a Kalam-style argument that I wasn't making. Second, abiogenesis doesn't "prove life can come from non-life." Abiogenesis is the research program investigating how life could have originated from nonliving chemistry. There are serious advances in prebiotic chemistry, but the origin-of-life problem remains unresolved. A 2026 review in Communications Chemistry explicitly states that there is still no credible complete model explaining how organic molecules were synthesized abiotically and how living cells emerged from nonliving components. A 2020 Nature Reviews Chemistry review likewise describes the integration of replication, metabolism, and compartmentalization into a self-sustaining evolving system as a major unresolved challenge. So "abiogenesis could explain life" is a legitimate scientific hypothesis. "Abiogenesis proves life came from non-life" is not. But here's the bigger point: Even if abiogenesis were completely solved tomorrow, it wouldn't solve the argument I'm making. Suppose scientists eventually discover exactly how the first living system arose from chemistry. Then we'd have: chemistry → first life. Great. But chemistry itself is still part of contingent physical reality. You would still have: Why does this physical reality exist? Why do these laws exist? Why these initial conditions? Why is there something rather than no contingent physical reality? Explaining one level of reality doesn't automatically explain why that level exists. And that's the key distinction you're missing: A scientific mechanism is not automatically a metaphysical explanation of why the entire system exists. Evolution explains how life diversifies after life exists. Abiogenesis attempts to explain how life could arise from nonliving chemistry. Thermodynamics describes physical behavior under physical laws. None of those propositions establishes: "Therefore physical reality is metaphysically necessary." That's the claim you'd actually need. You said, "God isn't the only way to explain physical reality." I agree. That's why I'm not presenting God as the only imaginable hypothesis. The actual alternatives are something like: 1. Physical reality is ultimately brute. 2. Physical reality is metaphysically necessary. 3. Physical reality is grounded in something beyond itself. But each requires an argument. If you say physical reality is necessary, then explain why its existence is metaphysically unavoidable. If you say it's brute, you've stopped looking for an ultimate explanation. If you say it's contingent, then the question becomes what ultimately grounds it. And that's exactly where the necessary-foundation argument begins. So the first law of thermodynamics doesn't establish an eternal or necessary universe, and abiogenesis doesn't establish that the origin of life is solved. More importantly, neither one answers the actual question: Why does contingent physical reality exist at all rather than not exist? Until you answer that question, you've given explanations for processes within reality, not an explanation of why contingent reality exists in the first place.
