intelligent agency must be ruled out altogether before unintelligent mechanisms can be concluded as 'most likely'
Intelligent agencies do not need to be ruled out. Look at how much progress science has made without involving that idea. Like the germ theory of disease, the heliocentric theory, quantum theory, the Big Bang theory, plate tectonics, relativity theory, and multiple other scientific and technological achievements such as space travel, the polio and smallpox vaccines, automobiles, and real-time global telecommunications, evolutionary theory needs no god and has no god in it.
Once again, that doesn't rule out the possibility of an intelligent designer or designers existing. It just means that to date, such information would be interesting, but superfluous. It wouldn't help us a bit to know or to posit.
Just look at the intelligent design research program, which assumes the existence of an intelligent. What has it profited them (scientifically)? What have they done that they couldn't have done without that idea?
I don't rule out spontaneous mechanisms, like the waves spelling help, it's possible, just not the most probable.
And I don't rule out the existence of an undesigned, uncreated god. It's possible, but not probable. In fact, I suggested that a god is the least likely thing imaginable to exist undesigned and uncreated, not a living cell, and not a universe comprising a handful of different types of particles and laws governing their interactions.
The rational skeptic rejects special pleading fallacies. Whatever reasons the theist proposes for his god existing is an equal if not stronger reason against it existing. Do you find a living cell too complex to exist without an intelligent designer? Then a god is even less likely to exist without one. You say that nothing can exist without a cause? The gods cannot exist without a cause. You say that a god can exist uncreated? Then so can a multiverse or a universe.
All such arguments are special pleading. The rule applies here but not there, and for no given reason. Just is.
Yet according to the tenets of atheist belief, our creative intelligence exists entirely undesigned
Nothing at all is true according to atheism unless you want to include that the atheist doesn't believe in a god or gods.
And we also don't assume the existence of creative intelligence prior to it evolving on earth.
If you want to revisit the argument using the entire list of universal constants instead... we can do that, but it's not going to help your case!
Actually, the fine tuning argument is more powerful support for a multiverse hypothesis than for a god hypothesis.
For starters, a multiverse that can generate countless copies of every type of possible universe would inevitably lead to universes like ours capable of generating stable galaxies of solar systems, life, and consciousness, and it would do so without requiring a conscious agent, making the hypothesis more parsimonious, i.e., preferred according to Occam's Razor: The simplest explanation that accounts for all observations is the preferred explanation.
Moreover, why would a god need to finely tune the physical constants in order for the universe to work unless that god was being restricted by laws that transcended it? How could such an entity be called a omnipotent if its choices were constrained to very narrow limits?
For that matter, what does a universe ruled by a creator god need laws at all? Planets could orbit their stars according to its will. Light could travel only so fast because this omnipotent god was propelling it that fast and no faster. It's a godless universe that requires laws in order to run unmonitored.
But "why throw out my true theory for your false one' is not up to your usual standards!
"True theory" is your phrase. I referred to an idea that works - is useful.
Nor did I call creationism false. That is also your language, not mine. I called it an idea that cannot be used for anything.
And you once again dodged answering why anybody should toss out an idea that works in favor of one that can't be used to inform choices. I assume that's because you have no answer. If that is not correct in this case, you probably ought to say why you don't offer a reason to replace what works with what doesn't.
Do you ever do that in your life - say divorce a wife with whom you are happy to replace her with someone that you will fight with, or quit a good paying job that is secure and makes you happy for a low paying one that is mind-numbing and soul-crushing and from which you are likely to be downsized out of?
If your answer is that you don't do such things, then perhaps you can understand why creationism is such a tough sell.
I like to see what actually works now- adaptation, and the strict limitations thereof, models that require outcomes to be predetermined, chemistry, physics, a reality that requires deeper instructions at the quantum level to operate, not merely a handful of 'immutable' Victorian age laws
You're misstating my position. What works is the theory, not evolution, or as you call it, adaptation. The theory directs us in ways that have improved the human condition.
