Wow. This is a new one on me. I went over and had a good peruse of the homepage - very reminiscent of Anatoly Fomenko, lots of obsessive fun'n'games with texts, and totally removed from Planet Earth. Unfalsifiable, because any objections can just be countered with the excuse of "copying errors". Didn't find any debunkers yet, but I'm not sure anyone would bother. You could check out the oddities on the forum, though - for example, a neat little discussion about how accounts of the life of Buddha were inspired by the life of Jesus/Julius...
