This is exactly WHY God inspired His word, because people are such idiots they think what they think is the truth.
So how do you "know", that is how do you tell which words are inspired? You rely on the authority of the church, on tradition, all these are human judgements. This book is included in the Bible as inspired and that book isn't. Humans made that decision. You are using your thinking and the thinking of other human beings to construct what you think the word of God is. And all the evidence you have are some copies of copies of scrolls that contain errors.
I see no evidence of God in all of that. I see evidence of the human psychological propensity to belief, to dependence on authority and tradition. In the case of the YEC'ers they take it to the extreme of denying reality in order to live like 500 years of science never happened. That is your choice but it is not science and doesn't refute anything science has developed.
The Bible is the inspired word of God in the exact same sense that the Vedas, the Koran, the Book of Mormon, or the teachings of Ramana are the inspired word of God, and that is because someone is willing to believe it is the case. There is no more evidence than that.
not to rag on the mormons much more, but it is my educated opinion that, for as many holes as there are in the bible, the bom is downright spurious in comparison.
I'm not crazy about the BOM either, but there are millions of Mormons who live their lives believing it as the delivered word of God. I can't distinguish their belief process from the belief processes of Jews, Christians, Muslims, Hindus, Bahai's etc.
I'm partial to the Upanishads but I don't take the myths in them literally and they could be wrong about some fundamental stuff. The jury is still out.
The sense I mean is found not in the books but in the believers. That believers convert from one religion to another demonstrates a similiar psychological process. Looking at a book all I see is something humans have written in a human language with human concepts. I can't tell from the book if its an inspired word of God. I tell that because there are people making that claim for it. (Well, I guess the Koran explicitly claims to be the word of God. I know little about it though.)
