It's sort of interesting that one of them came up with roughly the right age. However, the underlying reasoning seems somewhat dodgy, and I don't see anything to lift it up above the level of a minor coincidence.

"According to scientific rules, in order for critics to disprove the Torah codes, they would have to find fatal flaws in each of the six papers presenting a different approach and a different code. This happened five years ago, and to date not a single flaw was found in any of these papers. Therefore, for all intent and purposes, the Torah codes have been scientifically proven, and the debate is over."
