I own a book containing creation myths from every known culture - I think Christians and scientists would agree that all of them would look pretty silly in a museum, masquerading as literal accounts because many are completely ridiculous to the modern ear. So why do we feel the need to 'science-fie' the Genesis account? The reason scientists reject the idea is because we start with a conclusion, based on ancient literature and work backwards to prove it - it is the same reason that police detectives are not allowed to use evidence to support their own theories instead of allowing the evidence to point to what really happened. Without the Genesis account, the evidence uncovered by scientists supports evolution. If you feel the need to believe in a literal account of the Judeo-Christian story in Genesis, that is cool, but don't try to dress it up using science - that is just silly. We would be quick to dismiss all science if it concluded that a galactic turtle laid the planets or that the evolution of man from amino acids was received by a guru who was fasting under a lotus tree, because it would be seen as a competing religion - in fact, many Christians try to make science a religion so they have the grounds to do just that! Science rejects creationism because it is religion pretending to be science. My grandma used to have a sign on her fence, above her swimming pool that read 'I do not swim in your toilet so please do not pee in my pool' - indeed, what my grandmother lacked in refinement, she made up for in honesty and practicality.
