You can find explanations for all of those things online, skeptic, even on websites for kids where things are explained really step by step. Or you can take a free online course in evolutionary biology. Or you can get books from the library that explain it.
The fact is, you want us here to keep looking up stuff and writing up explanations for you, that you will still say do not make sense to you. We will do the research for you and explain how bones evolved. And you will say, but what about skin? Or fur? Or the eye? And we will do the research and write up another explanation. And you will say, but what about fingernails and saliva and the small intestine?
Why should we keep spending time doing that? I have decided not to. What would be the point? You go look it up yourself, and on science sites, not religious ones.
Then come explain to us how scientists think bones evolved.
Meanwhile, you can give us a rudimentary explanation of how god made bones, or why god decided to make it seem as though everything evolved. Why god left all those fossils lying around in the separate layers so you never get a dog fossil next to a dino, or a trilobite fossil next to a kangaroo. How the DNA record matches the fossil record so exactly and how geology, biogeography and climate science match up exactly as well. And, most importantly, how it is that applications of evolution (if it is so incomprehensively wrong and "stupid") have, over the past 150 years, constantly led to more accurate discoveries-- including improved crops, medical advances like antibiotics and vaccines, and better ways to solve crimes.
If evolution is wrong, how does it keep getting things right?
That is what needs explaining, not how bones evolved. We know how bones evolved. We don't know why god put them inside all the right rocks to trick us into thinking such a ludicrous thing as evolution really happened.
