You see, a lot of what has been posted is simply eyewash. A lot of ink has been spilled to expound on sometimes more sometimes less relevant things. The real pertinent issues are left unexplained.
What the heck is immaterial?
Where does non-intelligence end and intelligence begin?
What does it even mean for an immaterial entity to be intelligent?
Is it possible that such an entity creates stuff?
From nothing?
What exactly is personal?
And so on, and so forth.
This is actually a very good question.
The argument from cosmology states that the universe has a cause.
This has been established through science and philosophical argument.
Now, the point of this argument is to cause us to ask ourselves as inquisitive people are supposed to do:
What could this cause be? This is the real aim of the evidence. What does logic, reason, and rationality say should be the attributes of something that could cause the universe to be?
We are not required to know
how an immaterial entity could create a material universe, but the evidence does require us to maintain that it did.
With regards to (2).
I think we can determine where intellignece ends and non-intelligence begins by simply
looking at the effects of the entity in question.
I will use a rock and a watch as a simple example.
What are the effects of a rock? In other words, what does a rock do in and of itself? It does nothing. What is the immediate cause of rock formation? It is natural forces of compression of elements in nature. Are these natural forces intelligent? No. Elements, and pressure are not intelligent. They do not make decisions, they do not cause things to transform from random elements into designed entities with specified complexity and so on and so forth. Therefore a rock, is not intelligent. In other words it does not have a
mind.
What does a watch do? It tells us what time it is. What is telling time? It is a specific duration or length of time, in our case, 60 seconds making a mintute and so on and so forth. We see that a watch has a purpose.
What caused the watch to be? Random natural forces and elements? No.
A person caused the watch to be. An
intelligent being with a mind, caused the watch to be. This person or persons, designed the watch, machined the intricate parts, assembled them together, supplied power to power it and voila, an
intelligently designed material object!
Intelligence is indicitive of a mind. A mind is always indicitive of a personal being with volition (will), feeling (emotion), etc. etc.
There are plenty of issues that would need to be addressed in great detail. Instead there is paragraph after paragraph about causes, about excluded middles, and about whatnot.
These paragraphs are important for establishing a sound base from which to work, although most people do not need to know these ideas and concepts in detail to make accurate judgments about the world in which they live.
What you have posted is as if somebody were to make an argument for unicorns, and, this is the clincher, expouned long and broadly on the morphology, the feeding habits, the history and evolution of the horse. Maybe about how to ride them. The really important issues, the things that distinguish horses from unicorns, like the horn or the clover-shaped hooves, are not really argued for but rather introduced by sleight-of-hand trickery. Lastly, a connection to legends, stories and beliefs about unicorns is being made.
In other words there is a lot of talk. A lot of talk that is intended to give the appearance of having something to say. But all in all it is pretty weak and meager.
I am actually ecstatic that you have used this example of the unicorn!
I shall briefly take the time to expound on why your unicorn analogy is, at best, completely groundless and rather pointless.
What you have stated is that making an argument for God using the methods in the apologia, is nothing different than making an argument for the existence of a unicorn. You in a sense state that if one wanted to they could sit down and develop an argument with a lot of semantical gymnastics and sleight of hand trickery slide old unicorn into the mix.
This position contains a number of flaws, but for time sake I shall elaborate on four of them.
1. Sound reasoning - consistently followed - infers that an ultimate, uncaused, eternal, all powerful being must exist to make sense of the available data from science, philosophy, and other disciplines with regards to the cause of the universe. Sound reasoning and logic in no way make the same inference about a unicorn.
2. There is no reason to assume that a unicorn (if it exists) would possess the attributes akin to those of this Uncaused Cause which is required to accurately account for the existence of the universe.
3. Nothing that is known about the physical world infers that reality as we know it is the product of a unicorn. I.e., the universe and reality as we know it does not seem to have been the product of a finite, mysterious horse like creature with a horn on it's head that romps and runs through mystical forests.
4. The vast, well ordered universe which operates according to consistent observable principles which contains complex life forms all of which contain specified and irreducible complexity, human consciousness - all of these and more do argue for the existence of God. The universe and reality in no way appears to argue for a unicorn as it's cause. Our knowledge of the world around us does argue for the existence of an entity capable of creating the universe as we know it.
So you see my friend, this not only can apply to unicorns, but to any other mythological creature that your imagination may want to dream of.
Mr. Flying Spaghetti Monster, the Abominable Snowman, Santa Claus, whoever you like can be plugged into the unicorns place and none of them will be sufficient to bear the burden of the criteria demanded by the available evidence.
(Now of course I already know that apologists never have really tackled the important issues and that they are not going to address them either, and so can draw my own conclusion from that.

)
What might these important issues be?
