The fact that Ghidorah would have no explanation would only make him more ominous and unique among the monsters in the series. While Godzilla, M.U.T.O., and likely Rodan will have had finite, explained origins, Ghidorah will have no such background. It will confound the characters in the film as to where Ghidorah came from or why he is here. Making Ghidorah a terrestrial creature that somehow evolved on Earth will probably confuse viewers or give the impression of him being very unrealistic. Ghidorah would prove a good contrast to the other monsters. He would leave some element of mystery in a universe where the other monsters have explained origins. Sure it will leave questions, but it's better than making Ghidorah seem like a cop-out to make him more realistic by giving him the same origin as Godzilla. If Ghidorah were made mysterious and unexplained, it might manage to suspend disbelief more than just saying he's a creature like Godzilla, plus it might also keep at least some element of the unknown in the movie.
