I don't know where you're getting your information, but the Bible doesn't say God is "actively creating everything," whatever that's supposed to mean. He created the plants and animals "according to their kind" at creation, and they've adapted throughout the world using the built-in genetic variations within those kinds since then. God doesn't create new DNA with each generation. We can see and observe the DNA code degrade as mutations build up over time and genetic potential variability is lost.
Even your "artificial selection" of eliminating all long haired cats, using intelligence, doesn't result in any new information. It's a loss of genetic variability, which is what we see everywhere. We don't see increasing genetic potential, which is what evolution should result in.
Irreducible complexity isn't word salad, it's a very simple concept in various scientific fields. There's a certain amount of information or structure necessary for a certain thing to function. Think of a mousetrap for example. A mousetrap is basically irreducibly complex. It has the minimum number of parts necessary to function. If you remove one part, it's not a mousetrap anymore. It's just a collection of wood and metal parts that doesn't do anything useful. In biology, organs and systems have a level of complexity that's necessary for the part to provide a benefit to the organism.
Think of an ear. An ear is complex, with lots of different parts working together to capture sound waves, convert the sound waves to electrical signal, and send the signals to the brain. If any of those parts and systems fails, the ear no longer functions and you go deaf. It's not useful anymore, it's just a random collection of skin, bones, nerves, etc.
The reason this matters is that it eliminates the potential for the kind of gradual, imperceptible changes you claimed drive evolution. You can't evolve an ear with a huge number of tiny, imperceptible changes over eons of time. Until the ear is complex enough to function and perceive sound, it's useless to the organism and will be a liability that's selected against. That's the lower bound of irreducible complexity. Evolution has to account for a functional ear developing over a single generation, otherwise the claimed mechanism of natural selection won't "know" to save those new parts and keep improving them in the next generation. The whole idea is so silly it's hard to even steel man correctly.
The appendix is part of the immune system. Just because you can live without it doesn't mean it has no function. You can live without a finger or a toe too, and lots of people have those amputated if they get infected in a way that could be fatal. Just because scientists don't know the function or purpose of the tailbone, just like they didn't know the function of the appendix or the dozens of other "vestigial organs" for a long time, doesn't mean there is no purpose. Same goes for what was called "junk DNA" until scientists began discovering its purpose a few years ago.
I provided no evidence other than "the Bible says so?" So in other words you chose to reject the evidence I provided, and now you want to make it sound like I didn't provide any. Okay, that's your choice. I did my part.
I haven't seen that artist's conception of a so-called "firmament" in my Bible anywhere. You can find a picture somebody drew that has the word on it and depicts something imaginary that doesn't exist. That doesn't show anything about the Bible. I already told you the definition of the word. The fact that you found a picture that uses the word incorrectly isn't relevant.
