There are so many things wrong with this argument that I don't even know where to begin, but let's play along with this ridiculous line of thought anyway. The obvious question that follows is why is the "historical science" given by the bible any more plausible than the "historical science" of any other creation myth (http://en.wikipedia.org/wiki/List_of_creation_myths) ?
Of course there is a difference between circumstantial evidence and direct evidence, but even if you can't guarantee that your interpretation of the circumstantial evidence is true (something which by the way you can't do with direct evidence either), one should strive to find an interpretation that has the highest probability of being true given all the evidence at a given moment.
