If we accept, for a moment, that the Genesis account is an inspired work meant to convey the actual creation event. Would anyone have bothered with it if it was written as a literally correct description that no one would be able to understand for a few thousand years?
I look at it as like trying to explain ATM machines to pygmies. Now, to be sure, your average pygmy is, in my opinion, far brighter than your average American, but there is simply no way you are going to be able to literally describe how ATM machines work because they will have no frame of reference. Using technically correct terms like "electricity", "fiber optics", and "credit" won't convey anything meaningful, instead you need to relate these concepts to something your listener already knows by saying "Credit is like. . ." and even then there's no assurance of success. What you will end up with (if you fair better than me) is a meaningful portrayal of an actual concept that is, at the same time, not literally word for word true. Or you end up with comments like this:
"You mean, there's tubes under the ground with money shooting through them? Why doesn't anyone dig them up?"
