I’ll tackle all your mistakes here at once.
Again, it matters not what % of the universe is inhabitable for humans. Even for an atheist, in considering God creating the universe for men to worship him, the % of inhabitable universe is a non-factor, since you wouldn’t know how many humans God wanted to create or in how many places, to begin with. More deeply, the real #, whatever is it, is only a consequence of this incredibly wonderful physical paradigm. Which has quarks coming together to make sub-atomic particles, which make atoms, which make molecules, which make or can be made to make almost any kind of material or structure, including an amazing being we call Homo Sapiens. Along with the physical laws which work on the special properties of this matter, you have galaxies, black holes, dark energy, etc. It’s simply a matter of the essence of this physical paradigm that only a few planets will have the prerequisites for intelligent life. But it’s not a theological problem at all. As I said in my last post, though the bible is neutral on intelligent alien life, it makes complete sense to a Christian believer to have us be the only ones here, or so far away that we can’t communicate to others, since it is very difficult as it is for humans to fully focus on God, the way Jesus requires, in this world. Discovered alien life would be a major distraction. Look at the lack of physical descriptions of Jesus in the NT, there is more in Isaiah 53. Give God credit for being intelligent, he created this universe and left out almost all extraneous information on the physical representation of his son since he knows the weaknesses of humans (that was for free). In my view, the fact that we can’t even get a bleep of a transmission from anyone in deep space makes perfect spiritual sense. But all that matters not, nobody has any right to say that the % of habitable universe is an evidence against God, because no one outside of Himself has any idea how many intelligent life forms he wanted this universe to evolve.
How can anyone possibly say that this universe was created in an, “non-omnipotent” fashion? That is completely illogical based on the evidence. Maybe you are unaware, but the upper-limit estimate of the size of this universe 100 billion light years from one end to the other. Do you know how large a light year is? Light travels at 186,000 miles per second. At that incredible speed, it would take a photon 100,000,000,000 years to get from one end to the other. A LY in miles is ~5,879,000,000,000. Imagine 100 billion of those. That distance is unfathomable to humans, it’s only something we can write on paper. And this universe is expanding at a rate faster than the speed of light. And this universe contains, at latest estimate, 200,000,000,000 galaxies, each with 10 million to 1 trillion stars each. But, according to you, somehow something that large, massive and powerful is, “non-omnipotent”? It’s hard to put into words how utterly wrong-headed that notion is. You could just as easily state that God created this huge universe with only 1 planet evolving life to show us how special we are and how fragile life is.
“Competence” is a non-starter philosophically, but I’ll indulge you a little bit. Before I get into the details, let me quote from the high priest of positive atheism, Richard Dawkins. Describing a God that created a universe to evolve life, he said that such a god couldn’t exist because it would necessarily have to have an intelligence, “beyond understanding” to pull it off. To him, that excluded that possibility of God existing, because God would be too, “complicated” to account for. He completely botched that argument but it’s beside the point. Let me repeat, he said that God would have to be unimaginably intelligent to create the life-creating universe that you call, “incompetently” made. So, the length of time that it took us to get here is completely irrelevant to anything. As with % of habitability, length of time to get us here is only a consequence of the wonderful physical paradigm that God (or whatever) gave us and created us with. But what difference does it make for us? The world we inhabit, and our experiences would be exactly the same. God could have created us instantaneously if He had wanted to, but theologically he couldn’t have. That’s because in this paradigm, things change over time. If we were, “created” instantaneously, physical things would still evolve and change. Scientists would face a major discordance in what they would find and what they know they should find. And God at one point could be accused of being deceitful, creating something instantaneously that should have evolved to arrive at that point. It simply doesn’t make sense to create the universe of this physical paradigm, instantaneously. And that is just one angle. Creating a 100 billion light year large universe instantaneously takes out the 13.8 BY history that we know it has, removing a fair amount gravitas of this creation and putting man too close to the beginning, and in a sense to God, when it’s clear, to me anyway, that this place was created to see how great God is and to put us in our proper place in His creation. Beauty is in the eye of the beholder anyway. Many people think that such a gradual, nuanced plan to get us here such as cosmological and biological evolution as a divinely-inspired work of art.
