Ancient texts in discussions of science?

Written records are written by people and people lie and people tell stories. There are written accounts of Mount Olympus, Valhalla and Middle Earth. FYI they are not real.
Science is the study of physical evidence. Without physical evidence to corroborate written accounts they have little scientific value at all.
History/archaology is more dependant on written evidence but historians never claim that written records are anything but a subjective and quite possibly inaccurate clue to what really happened. I understand that the city of Troy although written of was not really thought to have actually existed until relataively recent physical evidence was unearthed.
As for taking the bible (or Koran or any other holy text) as scientific evidence - You might as well take the Illiad or the Lord of the Rings as your guide to physical reality.
