Against my better judgement, I'm going to break my rule of ignoring you.
I said explaining something by claiming a hidden mechanism that is beyond explanation is silly. And it is. You're only too blinded to see something so obvious. In fact, I can literally explain away anything I want using that logic. There is no gravity, only divine hands holding us to the ground. This isn't air I'm breathing, but the magical essence of life that is undetectably contained in the air. It is the silliest argument is the history of silliness.
When I was a kid I was still a believer (this isn't to belittle any believers, just a fact). I was around 10, and I would lie in bed for hours thinking about religion and god. And I had SO many doubts, but was still too young to have the desire or capacity to seriously investigate the subject. But as I wanted to so badly believe, I would always use the same argument to put my heart to rest; if there is no god, then where did everything come from? Just coincidence? Impossible!
See, that's the simplest possible argument for god. It requires no knowledge, experience, insight, or anything. It's almost instinctual. It is like thinking monsters hide in the dark. A meaningless statement that breaks every rule of logic. I explained why it is ridiculous a thousand times. But it's worthless. You'll only repeat the few catch phrases that you read on your religion forums.
And Occam's Razor states that given competing explanations, the one with fewest assumptions jumps to the front of the line. It has nothing to do with your simple-minded book analogy. If you find a book, the simplest explanation is that it was written by a human. There are competing explanations. Maybe it was written by an ancient race of elves that completely disappeared without leaving any trace. Maybe there isn't a book, but only a hallucination. Maybe it was written by the supernatural creator of all things to let us know how much it it likes rectangular objects. But Occam's Razor suggests we go with the first explanation. Don't you think?
