    Your claim to falsify "The universe was created" by appeal to the total body of knowledge is weak because it isn't possible to ascertain the total body of knowledge. I know further it is impossible to falsify because it is a metaphysical claim, just like the claim that "Forms exist" is a metaphysical claim. These are not scientific claims, they are metaphysical, and can't be proven or disproven unless they do make specific testable claims. So again, if I say that I believe the universe was created (I don't make that claim) then my belief is reasonable. Unless I exhibit a whole lot of other beliefs that appear to be unreasonable, in which case it might be legitimate to question the reasonableness of my beliefs in general.

    "The universe was created" is either vague and unsupported or entails things which are implausible given what we know. Was it an agent? Before the advent of stable systems capable of supporting agency? No, "like that but not".

    You're treating the claim "the universe was created" like it doesn't require any further explication - a description of how. Like a description of how is too much to ask. The reasons I don't believe it was created are because descriptions of how are implausible given what we know (for previously stated reasons; logically contradictory, equivocating, unsubstantiated, conceptually confused, inconsistent with little we do know about how the universe works), and if someone doesn't feel the need to say how, I have absolutely no reason to believe them.

    The issue is usually approached like the legitimacy of a creator comes from a hole in knowledge (dark matter, how far our universe description goes back does not include "the first instants") OR conceptual confusion (alleged regresses, prime movers not needing their own causal explanation, necessary to exist because a stated conceptual problem is allegedly impossible to solve without them, bad interpretations of science or pseudoscience (woo lives here) ). Then "a creator exists' is stipulated to be the end of the matter; as if no more questions need to be asked; as if how they did it need not be stipulated along with that they did it for the account to make sense.

    So again, if I say that I believe the universe was created (I don't make that claim) then my belief is reasonable. Unless I exhibit a whole lot of other beliefs that appear to be unreasonable, in which case it might be legitimate to question the reasonableness of my beliefs in general.Pantagruel

    This treats a person being reasonable as the same as a statement being reasonable. A reasonable person can have unreasoned or unreasonable beliefs; a person knowing how to reason in general does not entail that that person applies the competence in forming/supporting every belief they have. A better account stratifies the competences into domains, people know how to reason about some things but not others.

    When it comes to creator hypotheses, people often short circuit; they stop asking questions about how because apparently they have established that, and apparently that's that. When you start asking how questions, the claims are shown to be the confused and unsubstantiated drivel that they are.

    Anyway let's drop as it has become a question of the legitimacy of metaphysical claims in general which I'm not prepared to argue at this time. :)Pantagruel

    It's not about that at all, to me. Metaphysics in general is fine. It's simply because creator hypotheses are unsubstantiated on all of the details (and thus there's no reason to believe them), conceptually confused, entail logical inconsistencies or are implausible given what we know.

    People who believe they have demonstrated the existence of a creator would sooner believe their conclusion than examine the conceptual content of their own writing (assumptions, inferences, interpretations); questions cease. Why not pursue the next one instead?

    Who said it has to be justified?Pantagruel

    For claims like "there was a creator of the universe", which already play part in conceptual arguments and constrain empirical matters, the ability to justify them is presumed. If someone wants to behave as if they know there was a creator in such contexts, it's a performative contradiction (treating the claim cognitively until their ability to justify the claim ceases) and a conceptual error (knowledge claims need justifications) to suspend the need for justification.

    If a statement need not be justified in principle (in any context), it is not known.

    A belief is essentially a hypothesis.Pantagruel

    Hypotheses are implausible (and sometimes demonstrably false/wrong) when they contradict what we know, entail contradictions and require conceptual confusion and equivocation to articulate. I hypothesise that 1+1=3, but wait that's implausible. I hypothesise that the Earth is flat, or is that a matter of metaphysics? I believe that the universe is an egg and was hatched by the Great Chicken, it's fine to believe because justification is not required.

    Non-cognitive motivations make far more sense in most cases for belief in a creator or finding it plausible (well, more strongly, "seeing" the attraction). Questioning the claim's plausibility is felt to come along with questioning necessary human emotions, like hope and love and wonder.

    Many people (myself included) have an inkling, an expectation, a hope, that there is more to life than meets the eye.Pantagruel

We as humans are only familiar with a tiny fraction of what might exist and trying to say that everything in existence must follow the tiny fraction (of what we know) is a fallacy.

    I don't think this is relevant to the probability analysis of: 'is the universe a creation?. The material may or may not have pre-existed the universe timelessly.

    Whether there was intent to create life is not relevant to the existence of a creator so this point does not belong in the probability analysis.

    So I still get the initial probability of a the universe being a creation as 50%. To which all the positive evidence that the universe is a creation must then be added:

    1. Nothing can exist 'forever' in time - It would have no initial state so no subsequent states
    2. So everything in time is a creation
    3. So there must be a creator
    And
    1. Time has a start
    2. So time must be a creation
    3. So there must be a creator
    And
    Universe is not in equilibrium / Causality based arguments / Fine tuning / Big Bang

    That is quite a lot of evidence in favour of the universe being a creation.

    persons for systems of belief which are held, negotiated and challenged socially. If you relativise it to persons in that way, justification of a claim is entailed just by a person having a system of beliefs which coheres with it in some sense. This makes justification a personal matter, rather than a social one.

    It becomes justified to believe that one is Frodo Baggins if one believes that one's father is Bilbo Baggins; rather than listen to the rest of our socially distributed knowledge systems refuting it ("He's not Frodo, he's just high.").

    Coherence relations are justificatory relations between beliefs. They consist of (something close to) logical consistency (a logical property that two things can be true at the same time) + explanatory consistency (one claim supports or does not refute another). This is exactly the standard I've been using to argue that beliefs in a creator are unjustified; they entail contradictions and do not fit in with what we know, or are so vague and unspecified that they don't relate to anything at all!

    We simulate gross behavior and get general results. This simulation entails modelling from a pre-big bang state to the formation of 1st generation stars, to 2nd generation star systems with the building blocks of life and the conditions for abiogenesis- and determining in advance what life would look like. More importantly, when we model physical systems, we are applying known science. Observing and determining how the world works is of negligible complexity compared to designing how the world will work, from the ground up.

    God as the creator of spacetime cannot, by definition, be of spacetime (be of nature).

    God cannot have come into being; he must be timeless: all infinite regresses are impossible, that leaves only finite regresses, so causality must have an uncaused cause at the base. And it is only possible for an uncaused cause to be timeless (no 'before' - permanent existence).

    Agreed, but we are talking about a timeless architect of the universe. If time is not a constraint, it is possible to come up with anything. Maybe he went through 1000s of prototypes both simulated (in computers) and real before coming up with the Big Bang and our version of spacetime.

    The meaning of life is surely information - more information of good quality results in a better life. This applies to us and God equally. Which contains more good quality information - a non-life supporting universe or a life supporting universe? It is the 2nd, and that is what a god would seek to create.

    In addition, God is constrained by logic to being benevolent. That means given the choice between creating a non-life supporting universe and a life supporting universe, he would always take the 2nd path.

    I admit I am unsure about the existence of God. I think he probably exists is maybe as strong as I should state my belief. Multiple logical arguments point to the requirement for a god, but also dictates he must be very alien - timeless and uncaused - which makes me doubt the logic of his existence. I am, I think, basically a materialist but the requirement for God to exist versus the nature of God makes me even question my own materialist outlook. It is a fascinating problem.

    You're interjecting your prior beliefs about God, which means you're reasoning is circular. My original point stands that your fine-tuning argument depends on the assumption that life is a design objective. Since that entails a designer, you are basically assuming God exists in order to prove he exists; i.e. it's circular.

    I'm not trying to convince you God doesn't exist, I'm just trying to help you understand why "proofs" of his existence fail.

    Why couldn't the universe have simply existed forever? Or for that matter why couldn't it go forward in time a long ways, then loop back to the past, a circular model of time. Take the unit circle in the plane as a model of time. You just keep going 'round and 'round and there's no beginning and no end.

    Well, if the universe had no beginning then the past is infinite. So here we have the past as negative infinity as that's what you mean using the integers. Now consider the now to be any number on the integer number line: -3567, -9, 0, 1, 2019, etc. How do we reach these points? We'd have to pass through a positive infinity of time to reach these points. Now, is that possible? Of course not. Why? Think of the positive infinity {0, 1, 2, 3,...}. Can we pass through this positive infinity of time to reach any point that can be considered the present? Impossible, right? There has to be a beginning. It's not turtles all the way down.
    TheMadFool

    is not a point on the number line.

    For just a moment, forget that we're talking about time or causality. Just consider the number line of integers:

    .., -4, -3, -2, -1, 0, 1, 2, 3, 4, ...

    Nobody complains about it. It goes on infinitely in both directions, but there are no endpoints, Nobody ever says, "Well there MUST be a finite endpoint on the left but not on the right.

    Nobody ever says, "How could -4 exist? We'd already need -5 to exist. Etc. And the process could never start."

    Nobody ever says that. We take for granted that the integers go right and left forever.

    In particular there is no leftmost point that you need to "start from" in order to "reach" -4. Rather, -4 is right there. -4384378437 is there. Every integer is "just there."

    Why isn't it possible that time or causality are like that? Just because you have an intuition of a first element doesn't make your intuition right. As was noted recently, Buddhists have a very different intuition about the flow of time. You are simply expressing a Western cultural tradition. "In the beginning God created the heavens and the earth." That's essentially why you have such a strong psychological conviction that there must be a "first element."

    After all you are not arguing that we could never reach 5 "from the right." Why not? Past and future are symmetrical. Think of the block universe model of physics.

    To "reach -4 you start at ANY integer, and either move right or left a finite number of steps. There are no points at plus or minus infinity.

    Bottom line you're simply repeating your Western beliefs. But why can't time be eternal in both directions? Why can't it be circular? Who says it can't be these things?

    Akin to ... 'Causality must be caused' or 'A north pole must have a north pole' ... 'Strawberries must be made of strawberry-atoms'. or ... :eyes: :lol:

    3. An infinite regress ... is impossible
    False. Loops, circumferences, cycles, fractals, etc can be infinitely regressed ... Travel in a straight line, D99, in any direction on Earth and after traveling c24.9k miles you must arrive where you'd departed from because the Earth's surface is finite yet unbounded.

    Is infinity a Western Concept? I wasn't aware of that? Anyway...here's a simple argument:

    Suppose a distance of 100 km between points A and B. If we travel from A to B we cover a distance of 100 km. However if we were to travel in the reverse direction, from B to A, we still cover the same distance of -100 km. Right?

    Similarly when someone claims that there was no beginning, it implies an infinite past. Mathematically, if we take the present to be 0 on the integer number line then the past extends to negative infinity. That simply means that if we travel back into the past we would be faced with negative infinity and never reach a beginning point. However, like in my example of a 100 km distance between points A and B, if we travel from our past which is negative infinity to the present, point 0 on the integer number line, then we would have to traverse a positive infinity of time to reach the present, point 0 on the integer number line. However, positive infinity is, by definition, an interminable quantity and a task that cannot be completed.

    ...but we have no evidence of anything existing that is not part of spacetime, so you can't just assume it. Without evidence, it's merely a bare possibility - infinitesmal probability.Relativist

    We will never have any evidence of anything existing beyond spacetime because we are limited to space-time only. Without any evidence for or against, you can hardly assign an infinitesimal probability - that would be showing unwarranted bias against the proposition. Unbiased is 50%/50%

    You're interjecting your prior beliefs about God, which means you're reasoning is circular. My original point stands that your fine-tuning argument depends on the assumption that life is a design objective. Since that entails a designer, you are basically assuming God exists in order to prove he exists; i.e. it's circular.Relativist

    No it is not circular reasoning. I have a separate, very reasonable, hypotheses that all intelligent creatures (including any gods) would basically reason in the same way. A mind is a memory plus some logic circuits of some sort - so they must all work in a similar way. Right and Wrong can be defined in terms of net happiness and net sadness and these basic concepts would apply to all creatures. So any mind would be a logical device that understands right/wrong and has a memory. I can also prove that all intelligent creatures are benevolent, so we can add that constraint to the nature of God too.

    I'm not trying to convince you God doesn't exist, I'm just trying to help you understand why "proofs" of his existence fail.Relativist

    One can assign a probability to God's existence. Then any proofs help to modify that probability. And I enjoy coming up with proofs. And it is a very traditional philosophical pastime to try to prove the existence of God.

    You are confusing your evidence-free intuitions with a rational argument.fishfry

    You are failing completely to understand the dynamics of causal regresses. I have given you examples that I child could follow. I am almost at a loss. One more example:

    Imagine a perfect, frictionless pool table. The balls are wizzing around and will go on wizzing around for a potential eternity of time. Is this an infinite regress or can we infer an initial state where the balls were set in motion by the player?

    If you want to believe that time or the universe must necessarily have a beginning, you are free to make that assumption.

    I am suggesting that it is logically coherent to make the opposite assumption, and I offer the totally ordered set of integers as a thought-model or analogy.
    fishfry

    It is not logically coherent to assume that time has no start.

    Do you believe that a greater than any finite number of days has passed?

    Why couldn't the universe have simply existed forever? Or for that matter why couldn't it go forward in time a long ways, then loop back to the past, a circular model of time. Take the unit circle in the plane as a model of time. You just keep going 'round and 'round and there's no beginning and no end.fishfry

    If the universe existed for ever and its current state is X, then precisely state X has occurred a greater than any finite number of times in the past. Reductio ad absurdum, the universe has not existed forever.

    I think that a circular model is possible, but it still has a start/end of time at the Big Bang / Big Crunch. And a force eternal to the universe would still be required to cause the start of time (the Big Bang).

    What makes you so sure your model is correct, except for a vague feeling that there must be a first cause. Well then that first cause existed forever. You can't escape this problem by saying God did it.fishfry

    It's hardly a vague feeling, it's a logical certainty that a first cause is required as all infinite regresses are impossible. A first cause must be uncaused, IE beyond time. That then ties in nicely with the the 8 proofs I have that time has a start - a start of time also implies something from beyond time / causality.

    Explain why it is 'Petitio principii'.

    180 Proof

    The circumference of the earth is finite as is everything else. Actual infinity is impossible (see https://thephilosophyforum.com/discussion/7379/infinite-bananas/p1) so for this reason, infinite causal regresses are impossible

    Then the other reason that infinite causal regresses are impossible is they have no starting element and the earlier elements define the later elements - no first element means no nothing - infinite causal regresses cannot exist. They are like a house existing without its foundation.

    Fractals are not examples of infinite regresses; they are iterations that start known, defined, initial conditions. Any infinite regress has no starting point so none of it can be defined.
