Those are interesting ideas, and you are very right that ultimately the mind of God is unknowable.
My main issue is that, as you point out, everything seems to have been very well designed for us. The laws of physics seem perfectly written to support beings like us, and they also have a beautiful simplicity to them.
The universe beyond our solar system doesn’t seem designed with us in mind. Perhaps it isn’t. I suppose my worry is how much we matter to a God who has also created trillions of other worlds, if those worlds are not also eventually meant for us.
Much of the worldly press talks about possible worlds by focusing on the "goldilocks" planets. They talk as though that about the only parameter you need is for the planet to be just close enough to its host star (or stars) for water to not freeze, but just far enough away for water to not evaporate. I proport to you that they put so much focus on that one parameter that they want you to forget that there are literally thousands of parameters for a planet to be just right for advanced life. Such as:
The age of the planet relative to the age of its host star. An young star or a young planet can't host life. Nor can an old planet or old star. Our Earth happens to be just the right age, coincidentally at the same time the sun is at the right age.
The fact that there is just enough tectonic activity on Earth to stir up the heavy elements from deep within the planet and at the bottoms of the oceans for us to survive (our bodies need trace elements of heavy elements, including gold), while not enough to have too much of the heavy elements (gold is poisonous if we have too much) nor have too many earthquakes, tsunamis, and volcano eruptions to kill us all.
The fact that only Earth has a big brother size Jupiter planet that's just big enough and close enough to Earth to suck in comets and asteroids into its massive gravity well (preventing them from hitting Earth and causing Life Extermination Events every few hundred years like what killed the dinosaurs), but not so close and massive enough to cause too much tectonic activity on Earth or mess up the orbit.
And on and on and on.
