"Few"? Really?

There are some definite holes in FFVII's plot that are poorly explained or outright glossed over. This would seem to be a relatively minor incident of the latter. Though I suppose you could justify Meteor's existence as a necessary aspect of some sort of "balance." Because Holy was created, Meteor was a byproduct. So while I think it's possible to explain, like other parts of FFVII's plot, it involves making things up or further expanding on areas not very well developed in the game.
