This argument doesn't stand up well in this case. While it might be the case that the probability of Some universe coming into existence might be somewhat high, the life permitting universe is very low from what we've observed.

Let's see the math. Start with "what we've observed" about the probability distribution of the values of fundamental constants from all the universes "we've observed" coming into existence and go from there.

Since when have garbage men, religious or otherwise, been authorities on the physics of the very early universes?

About as long as physicists have been publishing peer reviewed papers demonstrating that god is responsible for them.
You must have missed my point. The fact that physicists have opinions about stuff that requires faith to believe doesn't say much, other than that they're humans. Their faith isn't any more useful in figuring out reality that any other. Get back to us when they have well tested models which match their faith.

The significance of this universe is that it is one of the extremely few where chemistry can happen, compared with the countless trillions upon trillions where that isn't possible.

And all you have to do is show - based on our observations of how universes for - how unlikely it is that life-supporting universes can form. Shouldn't be that tough, given how many we've observed in the lab...

That's the main point here. There's a difference between "lots of possible outcomes" and "all outcomes are equally likely". Think about how many possible outcomes there are when flipping a coin - it could land on its side, it could teleport to the far side of Alpha Centuri, it could spontaneously convert itself to energy, and a billion other possibilities. But it always seems to be "fine tuned" to come up heads or tails rather than those "countless trillions upon trillions" other possibilities. But since we know that those are the two most likely options no one is surprised.

When trying this with universes, it is all just guessing as to what the odds are.

My question would be: why are you so surprised that we find ourselves in a universe in which we can exist?


What best explains the universe and its very narrow parameters that allow for intelligent life to exist?

It's not even clear to me that this requires an explanation.
Any universe would be "fine-tuned" for the stuff found in that universe.

My view as the theist is that God better explains the fine tuning of the universe than a purely atheistic naturalistic explanation.

How does a god explain anything at all?

Keep in mind what an explanation actually is when answering that question.

It is from what we know that the fine tuning argument stems.

Really? Then why must the question be asked "what explains the specific values of these parameters?"

The very fact that question needs to be asked, proves that there are no answers as of yet.

That's quite literally "we don't know, so we'll just say god dun it".

Not to mention that many of those quotes mention the appearance of fine tuning rather than evidence of actual fine tuning.

I should not have missed that. Just as Dawkins used the phrase "appearance of design". Many creationists cannot understand that he is saying that it is not designed in that little phrase.

What support do you have for that statement?

The universe existed before life.

If life is going to come into existence in a universe, it will be the kind of life that can actually exist in said universe.

To have chemistry you need the heavier elements. To have the heavier elements you need stars. To have stars you need gravity to be fine tuned by one part in 15 million.

And does the "one part in 15 million" the case so that stars could form?
Or did stars rather form as a result of the "one part in 15 million" being the case?


Is a rock sharp for the purpose of cats being able to rub their head against?
Or does a cat rub its head against said rock, because it happens to be sharp?


Any more, and the universe would have collapsed back in on itself shortly after the big bang. Any less, and the universe would have expanded to quickly for stars to form.

But it is the value that it is. So stars could form.
What is the mystery here?

It does not matter, you are still wrong.
About what? You just keep saying I'm wrong and I haven't even gone into my personal argument yet. This tells me that you have set yourself against whatever I say because I am a "Creationist" and you don't really care what I say because I am starting out wrong in your opinion.






I have on some, you either paid no attention or did not understand. If you want to go over some claims of yours in more depth I am happy to do so.
No, you haven't supported anything you've claimed other than link to the article that I quoted from.



And if I have time later tonight I will post it if I come across it again. Or you could do what I did to find it. Simply Google search the quote you made at the start of this thread.
Right.

"if things were different, then things would be different".

Sounds like stating the obvious.

Well yes, that is obvious. That is what is at issue. The chemistry and many other elements were necessary to make it possible to come about.

It seems to me that by "necessary", you actually mean "meant". Is that correct?

Your entire "fine tuning argument" seems to imply that the universe was meant for the purpose of bringing forward life. Is that correct?

If yes, what is your evidence for this?

Don't blame others if you have not started your personal argument yet. And you should not take offense so easily.




No, you haven't supported anything you've claimed other than link to the article that I quoted from.

Now you are wrong again. I gave you a specific example, it is well known, I did not think that a link was needed, but if you need a link explaining how Newton's Law of Gravity explained Kepler's Laws I will be more than happy to give you one.



I actually searched for it again and found it and linked it. Then I noticed that I still had the article open on another tab all along

How other universes would somehow make our fundamental constants not constants. Please explain.

Then they would be "constants" only in our universe. They would not be actual constants if they were variable. The whole argument relies on the concept that these "constants" could have been different, if they could have been different they are not constants.

There were many factors that allowed for stars to form. Those are the parameters that we are discussing when we are looking at the fine tuning in the universe to allow for intelligent life.


... in hindsight. Teleological fallacy.

Here's a thought exercise for you...

Think back 5 generations in your bloodline.
2 parents.
4 grandparents.
8 great grandparents
etc

For YOU to exist, all those people had to meet, come together and have a child.
During the act, millions upon millions of sperm cells were deposited. Only one of which would result in the specific person in the family tree.

Imagine all the different parameters, variables etc that had to be "just right" in order for YOU to exist.

Imagine all the things going on in the lives of those people. The epidemics of flu and other deseases they survived, the wars, etc

So, was the past "fine tuned" so that you could exist?

That's the main point here. There's a difference between "lots of possible outcomes" and "all outcomes are equally likely.

The point is that something needs explaining. There are several strategies amongst atheistic scientists for coping with that. One is to suggest that we live in the only universe which can exist, because, for reasons unknown, the fundamental constants must have the values they do have. Another is to postulate a multiverse, containing a near infinitude of other universes, and we just happen to live in one of the few with chemistry. Another is to flatly deny that there is anything which needs explaining.

With regard to the last, one wonders, if there is nothing to explain, why their atheistic colleagues try so hard to come up with an explanation not involving God. With regard to the multiverse, Leonard Susskind has admitted that the motivation for suggesting a multiverse was to diss the theists, who saw in fine tuning a pointer to God. The first suggestion mentioned above has the ring to it of a similarly ad hoc hypothesis.

What makes a theistic explanation different is that God is not a hypothesis recently dreamt up to explain away some recently discovered facts.
