OK, 1st, I'm lazy, and haven't read the whole thread yet. But here is some food for thought:
When Genes mutate, they generally mutate in a bad way. Between a generation, genes may not be created, but certainly genes are lost, or damaged. In fact, this is how people track their ancestors, by what missing genes they have in common. Rarely, if ever, is a new gene or sequence of DNA created between a generation.
Just think of your genes as a book, lets say, Shakespere.

Shakespere's plays have been copied and copied, rewritten and rewritten. As a result, we now have many different variations of Shakespere's plays. OK, so you're saying 'evolution!'.
However, do you think that any of these varitations were better than the original? The original was the one that was famous, known all throughout London. These badly copied versions are inferior, and less Shakespere. The same can also be said for the Lord of the Rings. The original publisher made a tonne of mistakes, other publishers copied those, made more, and it was a real mess to fix. The bible is a bad example, BTW, because only a handful of name spelling differences have been found.
Same goes for genes. After copying and copying, The book will not become a better, more accurate story. It will get worse, and worse, and the errors will have errors made on them, and those errors, errors on them. Reproduction is just the publisher reprinting the book of Genes.
