It's crap. In order to make the "prophecy" work, it has to be changed to a metaphor, rather than superstitious man believing in a real splitting as a sign of the end of the world. Turn anything into a metaphor and you can make anything into anything. Sort of like Jesus saying he will be back in their lifetime, and then changing lifetime to mean they have eternal life and so it will be at the end of days, which no man may know.
Crap.
Crap.
