Some fundamentalists now allow for the possibility that Noah's flood may have occurred a few thousand years earlier than the date a very strict reading of the Bible's chronological record indicates. (That date, as published by James Ussher over 350 years ago, is 2350 BC) They do so by saying that there may be some "gaps" in the Genesis genealogies.
Whitcomb and Morris, in the final paragraph of their book The Genesis Flood, wrote, "It would seem to us that even the allowance of 5,000 years between the flood and Abraham stretches Genesis 11 almost to its breaking point. The time has come when those who take the testimony of God's infallible word with seriousness should begin to look with favor upon the efforts of those who are examining and exposing the unwarranted assumptions and false presuppositions of uniformitarianism as it applies to the dating of early man."
In other words, fundamentalists believe that they should always put their belief that the Bible definitely teaches that our planet was completely flooded with water just a few thousand years ago ahead of the findings of modern science when it comes to determining how long mankind has widely, and continually, inhabited our earth. Their reaction to stories such as the one you just posted is always to say, "The findings of scientists pertaining to the dating of early man must be in error, because our interpretations of the Bible cannot be."
