The largest problem in this debate is that somehow, in the minds of many Christians, believing in Young Earth Creationism has become equivalent to believing in the Bible as the Word of God. It has been pounded into their heads that you reject God if you believe in evolution. Until this changes, you will continue to see stupid stuff like this.
YEC is not only very bad science, but poor biblical scholarship as well. A careful reading of the third chapter of Genesis will reveal that the laws of physics changed due the fall of man (Somewhere between verses 14 and 19. Of course, God being God, he can do this at his pleasure). For example, the fundamental laws regarding increasing entropy could not have existed before the fall (At least, it could not have existed as we know them today). My personal theory is that the change to the natural laws took place gradually, finishing at the Tower of Babel, with time sort-of "collapsing" in both directions. (Fits the gradually decreasing life expectancies up to the flood, and the fact that it is about the period in history when the archeological evidence and the Bible start to match up, though not perfectly I admit)
The biblical bit of this is, of course, mostly useless from a scientific standpoint. But from a religious standpoint, neatly severs, as should be the case, The Science of Really Old Things, and Religion.
