Expansion/explosion, depends on how you look at it.
No — it does not “depend on how you look at it.â€
In physics, an explosion is:
• matter expanding into pre-existing space,
• from a local centre,
• into an external environment.
The Big Bang is:
• the expansion of space itself,
• with no external space,
• no centre,
• and no surrounding environment.
Calling it an “explosion†is not a harmless synonym; it imports false causal intuitions. Precision matters here because your analogy relies on that imprecision.
SiNcE_1985 wrote:
Many events, over billions of years, right?
Yes — and that point undermines your own analogy.
Once you acknowledge multiple stages governed by different mechanisms (nucleosynthesis, chemistry, replication, selection), the “single chaotic unguided explosion†narrative collapses. The explanatory work is being done by lawful processes, not by time magically “saving†anything.
SiNcE_1985 wrote:
Fine tuning is required for any of that stuff to occur.
This is a separate argument, and it does not do the work you think it does.
Fine-tuning arguments concern boundary conditions of physical constants. They do not:
• imply intelligent design of biological structures,
• override evolutionary explanations once chemistry exists,
• or establish a personal creator.
Even if fine-tuning were granted, it would at most motivate cosmological speculation — not refute evolution or reclassify it as religion.

So, time is indeed the savior for most things scientific.
Time is not a “saviorâ€; it is a parameter.
Time alone does nothing. Without:
• variation,
• inheritance,
• selection,
• and constraint,
nothing happens — regardless of duration.
Evolution is not “given enough time, anything can happen.†It is “given specific mechanisms, certain things become likely and others impossible.†That is exactly why it is testable.
SiNcE_1985 wrote:
the universe is indeed a closed system.
This does not rescue your entropy argument.
Yes, but within the closed system of the universe, there are many locations that are not closed systems, for example, as I mentioned in my previous post, the Sun provides energy to the Earth. There are an estimated two septillion stars in the observable universe.
The second law of thermodynamics says total entropy of a closed system tends to increase.
It does not say entropy must increase everywhere or at every scale.
Local decreases in entropy are:
allowed,
expected,
and unavoidable,
as long as they are offset by larger increases elsewhere.
That’s why:
stars form,
galaxies form,
crystals form,
weather systems form,
embryos develop,
and life evolves.
All while total entropy still increases.
Low-entropy initial conditions are not disputed. What fails is your inference that this implies design of biological complexity.
Entropy arguments:
• do not distinguish design from natural law,
• do not predict DNA, proteins, or organisms,
• and do not block local complexity once gradients exist.
Penrose’s calculation concerns the improbability of initial cosmic smoothness — not the impossibility of evolution given that condition.
You are moving illicitly from:
“low entropy initial state†→ “therefore intelligent design of life.â€
That inference does not follow.
Cosmological fine-tuning: what it is (and isn’t)
Cosmological fine-tuning concerns:
the values of fundamental constants (e.g. gravity strength, cosmological constant),
the initial conditions of the universe (e.g. low entropy, smoothness),
the existence of long-lived stars, chemistry, and stable matter.
The question it addresses is:
Why does a universe capable of complexity exist at all?
This is a boundary-condition question about the universe as a whole.
What fine-tuning arguments can legitimately support
At most, fine-tuning arguments can motivate:
philosophical curiosity,
speculative metaphysics (e.g. necessity, multiverse, brute fact),
deistic or non-specific creator hypotheses (logically, not evidentially decisive).
They do not identify:
a personal God,
intentions,
moral character,
biological design,
or intervention in evolution.
Fine-tuning lives entirely at the cosmological level.
What fine-tuning does not do
Fine-tuning does not:
explain how stars form,
explain how chemistry works,
explain how life originates,
explain how species diversify,
override lower-level physical or biological explanations.
It sets the stage. It does not write the script.
Biological evolution: what it is (and isn’t)
Biological evolution explains:
how populations change over generations,
how complexity can arise incrementally,
how adaptation occurs without foresight,
how diversity branches from common ancestry.
The question it addresses is:
Given a universe with chemistry and replicators, how does biological diversity arise?
This is a mechanistic, mid-level causal explanation.
What evolution assumes (minimally)
Evolution requires only:
replicating entities,
heritable variation,
differential reproductive success,
physical law consistency.
It does not assume:
atheism,
metaphysical naturalism,
absence of God,
denial of purpose.
It is agnostic about ultimate origins.
What evolution explains extremely well
Evolution:
predicts nested genetic hierarchies,
explains fossil succession,
accounts for antibiotic resistance,
explains speciation and extinction,
unifies biology into a single framework.
It does real explanatory work within the universe.
Why entropy and fine-tuning cannot be used against evolution
This is the key separation point.
Entropy applies at the cosmological level
Low entropy initial conditions are about the early universe.
They explain why energy gradients exist.
They do not dictate what happens locally once gradients exist.
Evolution operates locally
Life exploits energy gradients.
Local order increases while global entropy still rises.
This is expected, not exceptional.
Here is the structure that avoids confusion:
Cosmology asks: Why is there a universe capable of complexity at all?
Physics asks: How do matter and energy behave in that universe?
Chemistry asks: How do complex molecules arise?
Biology asks: How do self-replicating systems diversify and adapt?
Each level:
presupposes the previous,
does not compete with it,
and is not invalidated by unanswered questions upstream.
Abiogenesis asks:
How can non-living chemistry give rise to systems that:
• self-maintain
• self-replicate
• transmit heritable information
• undergo selection
It does not ask:
why the universe exists,
why physical laws are what they are,
why chemistry works,
why evolution works once replication exists.
It asks how replication itself begins.
Why abiogenesis is not part of evolution
This is critical.
Evolution by natural selection requires:
replicators,
heritable variation,
differential reproduction.
Abiogenesis investigates how the first replicators emerged.
So:
Evolution ≠abiogenesis.
Evolution does not presuppose abiogenesis is solved.
Evolution is silent on ultimate origins.
Rejecting abiogenesis does not refute evolution.
Abiogenesis research investigates:
autocatalytic chemical networks,
RNA-world scenarios,
lipid vesicles and protocells,
energy-driven chemical cycling,
self-organization under non-equilibrium conditions.
It does not claim:
“life came from nothing,â€
“a cell assembled all at once,â€
“complexity popped into existence randomly.â€
It studies gradual transitions, constrained by chemistry.
Abiogenesis is difficult because:
it happened only once (as far as we know),
it leaves sparse direct traces,
it occurred billions of years ago,
it sits at the edge of chemistry and biology.
That makes it:
underdetermined,
experimentally indirect,
but still a legitimate scientific problem.
Hard ≠religious.
Unsolved ≠unscientific.
Even if abiogenesis turned out to be:
extremely rare,
improbable,
or dependent on narrow conditions,
that would not:
invalidate evolution,
imply intelligent design of organisms,
or justify calling evolution a religion.
Does cosmological fine-tuning support any specific God?
1. What fine-tuning actually targets
Fine-tuning arguments concern:
physical constants,
initial conditions,
low entropy beginnings,
life-permitting ranges.
They ask:
Why does a universe capable of complexity exist at all?
They do not ask:
why DNA exists,
why evolution works,
why humans are moral,
why religions differ.
That matters.
2. What fine-tuning can support (at most)
Even if we grant fine-tuning fully, it supports only this:
Some explanation may be required for why a life-permitting universe exists.
That explanation could be:
brute fact,
necessity,
multiverse,
unknown physics,
deistic creator,
abstract ordering principle.
Fine-tuning does not discriminate between these.
3. Why fine-tuning does NOT support any specific God
To support a specific God (e.g. the God of Islam or Christianity), fine-tuning would need to predict things like:
revelation,
miracles,
moral commandments,
incarnations,
scriptures,
salvation narratives.
It predicts none of these.
Fine-tuning is:
morally silent,
theologically silent,
culturally silent.
It gives you at most a cosmic “why,†not a religious “who.â€
4. Why fine-tuning especially fails to support Christianity or Islam
Both Christianity and Islam require:
historical miracles,
specific revelations,
moral laws,
divine intentions toward humans,
intervention in history.
Fine-tuning explains none of that.
A universe fine-tuned for:
stars,
chemistry,
long-lived structures,
is equally compatible with:
deism,
panentheism,
non-personal necessity,
or even non-theistic metaphysics.
Jumping from fine-tuning → Jesus or Muhammad is an unsupported leap.
5. The crucial mistake people make
They do this:
Fine-tuning raises a deep question.
Deep questions feel meaningful.
My religion feels meaningful.
Therefore fine-tuning supports my religion.
That is psychological resonance, not inference.
SiNcE_1985 wrote:
That is the only point and cannot be proven wrong.
That statement alone disqualifies it as an explanation.
If a claim “cannot be proven wrong,†it does not explain — it terminates inquiry. Science advances precisely by preferring claims that can fail.
Appealing to irreducible intuition (“it just must be designedâ€) is not an argument; it is an insistence.
SiNcE_1985 wrote:
every claim must stand on its own merit.
Agreed — and evolution does.
It stands on:
• genetic hierarchies,
• nested phylogenies,
• observed speciation,
• predictive biogeography,
• experimental evolution,
• medical and agricultural application.
Analogies are not doing the work here — evidence is. I have a biological science degree in which I studied evolution. Have you actually studied evolution? It doesn't look like you have.
SiNcE_1985 wrote:
A transcendent first cause is necessary.
Necessary for what?
A first cause may be posited to stop infinite regress, but:
• it does not explain biological mechanisms,
• it does not predict evolutionary patterns,
• it does not constrain outcomes.
“First cause†is a metaphysical stop-sign, not a biological explanation.
Calling termination “the best explanation†confuses
closure with
understanding.
SiNcE_1985 wrote:
If you can prove the natural origins of the universe, life, or consciousness…
This is a misplaced burden of proof.
Science does not require final, total explanations to justify provisional models. We did not need to fully explain combustion before rejecting phlogiston.
Evolution explains diversification.
It does not claim to have solved cosmology or consciousness.
Gaps elsewhere do not convert a well-supported theory into a religion.
SiNcE_1985 wrote:
the more complex A is, the more ID is required.
This is an unsupported premise.
Complexity arising via:
• cumulative selection,
• replication with variation,
• and constraint,
is categorically different from engineered artefacts.
Saying “more complex therefore designed†is not an inference — it is a preference.
SiNcE_1985 wrote:
mindless/blind processes can’t build automobiles
Correct — because automobiles do not reproduce.
Your bench-press analogy fails because evolution is not a strength contest; it is a population process.
Nature cannot build cars because cars lack heredity. Nature builds organisms precisely because organisms reproduce with variation.
SiNcE_1985 wrote:
Purpose and function is the evidence for a designer.
Function does not entail foresight.
Selection produces function without intention. This is not controversial — it is observed in real time (e.g., antibiotic resistance).
You are inferring intention from outcome, which is the very mistake evolutionary theory was developed to avoid.
SiNcE_1985 wrote:
Abiogenesis/evolution does everything my God did.
No — it does something very different.
Evolution:
• explains mechanisms,
• constrains outcomes,
• risks falsification,
• improves prediction.
Your God:
• explains everything equally,
• forbids nothing,
• predicts nothing specific,
• and cannot be tested.
Calling evolution “natural deism†is rhetoric, not analysis.
Final clarification:
This debate is not about labels you dislike or prefer.
It is about a simple distinction:
A religion explains by authority.
A scientific theory explains by constraint.
Evolution constrains.
Intelligent Design does not.
Besides, the flaws in organisms show that no intelligent design occurred.
Until an alternative:
• specifies mechanisms,
• forbids outcomes,
• and predicts novel facts,
calling evolution a religion does not undermine it — it only signals disagreement with its implications.
Intelligent Design begins by noticing a real boundary problem (origins), but it immediately jumps explanatory levels instead of crossing them. Biological evolution explains how life diversifies once self-replicating systems exist; it does not explain why the universe exists, why chemistry is possible, or how the first replicators arose. Intelligent Design collapses these distinct questions into one by treating evolution as if it were a cosmological origin theory, then criticising it for failing at a task it never claimed to perform. Difficulty in abiogenesis (chemistry → biology) is then illegitimately used to invalidate evolution (biology → diversity), even though the two are sequential, not competing explanations. That is a category error, not a refutation.
The decisive failure comes when Intelligent Design replaces mechanisms with agency. Invoking a designer specifies no mechanism, imposes no constraints, forbids no outcomes, and generates no testable predictions — every possible world remains equally compatible. That means the hypothesis does not explain why this world exists rather than another; it merely terminates inquiry. Complex biological systems are not engineered artefacts but self-replicating populations shaped by selection, and importing artefact reasoning across levels is exactly where the argument breaks. An explanation that fits every possible outcome explains nothing — and that is where Intelligent Design fails.
