I didn't say that efficiency was the foremost goal. The point is that things that are unnecessary don't have a purpose except to be a part of showing how the universe designs itself.
I know you didn't say that explicitly, but I saw it as a presupposition because here's what you said, slightly rephrased, "If everything can be made instantly and magically, what purpose is there in processes that develop things naturally?" This compares two options, one whose primary benefit seems to be that it is done "instantly" -- and
that is typically only useful when your goal is to be efficient, right?
So the answer to your question has to be something which posits that even though instant, "magical" creation was possible, the Creator had a higher purpose than to simply gain efficiency by doing it that way.
You asked what the universe would look like in my/our opinion if it was designed (I know you weren't talking to me, but I jumped in anyways). I told you what features I would expect (and have read other people say what they would expect). It isn't about proving what a designer would do in some universe, it's about what isn't done in this one to show design.
So are you saying the attributes it would have to have are (1) it is very simple, (2) it is very small, and (3) it is totally inexplicable? Really? That's how you would know it is designed? Let me just stop there and make sure I understand that correctly. I'll let you confirm.
The only attribute you could add to this universe to show that it has a designer is the irrefutable being saying "I created this". I know that is going to be something you call unreasonable. Of course I don't see why. Creating a universe is a big deal, showing up and taking credit should be trivial.
Just because showing up and taking credit would be trivial, it does not necessarily follow that this is something desirable from the vantage point of the One who is responsible for creating us, at least not how you may be envisioning it (perhaps via some giant television screen in the sky on the "BigGuy Network" channel). Being that we are discussing this on a Christian forum site, I'm sure you are aware that Christianity claims that someone
did show up and take credit for it. So your beef should be about whether or not you believe this person and the accounts of what He claimed, not why no one showed up claiming to be the Creator.
So the question is what should be taken away to show signs of a designer. And that would be the way that we can see how the universe shapes itself including it's inhabitants.
We can see and calculate how a nebula forms into a star and then see how planets form themselves out of dust and rocks. You may disagree, but we can see how life becomes more complex, changes, and becomes more intelligent and advanced. Evidence of a designer comes from these things happening straight out of the designer, and not out of natural processes that control these things themselves.
If you knew nothing about how a symphony got recorded but could listen carefully as many times as you wanted, how would you know that it was designed by a composer rather than occurred "naturally" somewhere? You would observe nothing that appeared to come "straight out of the designer", you would only hear patterns, see themes and variations, hear melodies unfolding seemingly entirely on their own and without any help. There would appear to be rules about which harmonies land on which beats, but would you assume that the rules and patterns just "magically" existed on their own as natural occurrences?
Perhaps you would. But you see how wrong you would be, because it was only your knowledge that was limited. The simple fact which Christians do not understand about your point of view is why everywhere else in life we look for those
elements of design to discern what was
designed and what was not (just think of archaeology, alone). But when it comes to the universe, you demand to see that big hand at work, or an owner's manual telling you how it's all made and how to fix stuff. That's what just doesn't make any sense. It is both reasonable and intuitive to see all of these
elements of design and conclude that there is a designer.
So you may disagree about the evidence we have for evolution, and that is a whole other topic for a whole other board, but as long as we can see ways that a designer is unnecessary, then we see signs that a designer does not exist. What we need to show evidence of a designer, is a lack of evidence that a designer is unnecessary.
You're not making any sense. That's like watching the symphony orchestra perform, and deciding that a composer was not necessary because the music is clearly organizing itself all on its own. Don't you know the difference between a design and a medium for executing the design? In the universe you are only seeing the forces which act as the orchestra that is executing what was scripted for them by the composer. Why would God need to explain to you exactly how He "speaks" a command and the elements obey Him (metaphorically speaking)? He came and did miracles so that you knew He had the ability to command the elements. Argue that if you want. But don't try to tell me that a designer is unnecessary just because He's not directly standing there pulling the strings or playing the instruments.
So much of what we have thought required a designer no longer requires one (think about gravity, natural disasters, disease, etc.) that there is good reason that the things we can't explain yet will be explained someday. Maybe not even someday soon, but someday. What reason is there to believe that what we haven't explained yet, won't ever be explained given how much we have explained thus far?
Even if you resolved the grand unified theory in one elegant equation, you would still have to explain who the heck put it there for you to discover. You still have the problem that all of this stuff has the elements of
design written all over it, and yet you're going to insist that there is no designer despite that evidence and despite the fact that someone
did come along and not only claim to be the Creator but perform things only a superhuman (above human) Creator would be able to perform.
