First, the truth of Scripture must be held inviolable. Secondly, when there are different ways of explaining a Scriptural text, no particular explanation should be held so rigidly that, if convincing arguments show it to be false, anyone dare to insist that it is still the definitive sense of the text. Otherwise, unbelievers will scorn Sacred Scripture, and the way to faith will be closed to them (Summa Theologica, Vol. 10:71-73 of the Blackfriars 1967 edition).Whether we're talking about the age of the earth, the methods God used to create, or the historicity of Adam of Eve, there is no doubt that there are different ways of explaining the text. So, following Thomas's advice, let's not hold to a particular explanation so rigidly that when convincing arguments come (and they will probably come) that the way of faith will be closed to people today. I've seen this too often lately. People who have said, "If this is what Scripture says, then obviously it is a bunch of a hooey."
