Just a little titbit from me. The age of books and things like that is estimated using the same technique that is used for dating the age of the planet to much older than the Bible implies through its creation story - the analysing of proportions of isotopes in conjunction with their half-lives - for books, specifically comparing against the expected content upon "formation" (the time when the tree is killed to make the book.)
As far as the bible being scientifically sound is concerned, I think very few secular scientists agree that the world was made in a day some five thousand or so years ago or that an intelligent designer made all life. It is also the case that the scientific method involves forming a hypothesis and performing experiments with the aim to then explain it using current theories or to form a new theory to do so; one cannot simply state something about the physical laws and hope it turns out to be true. It is also important to not mistake knowledge placed in a holy book for knowledge of the community at large at the time rather than supernatural knowledge given by a non-terrestrial being. There were major and advanced civilisations before Christianity and their Gods were dismissed as false when the people progressed.
