And since the presence of so many intellectually-challenged people on this planet chafes my ass so, let me also add this little bit of perspective ... Few all-time classic giant monster movies actually explain the origin of the featured creature. The first true giant monster film was the 1925 silent version of THE LOST WORLD. No real explanation is given in that movie (or in Sir Arthur Conan Doyle's novel, or in any of the subsequent film and TV adaptations) for the existence of dinosaurs and other prehistoric creatures on a plateau in modern times. They're just there, having somehow defied extinction. The same is true of KING KONG, in every one of his screen incarnations. No gorillas that size exist today, and none appear in the fossil record. None of the film versions of the Kong tale explain why one exists on Skull Island, or why it shares the island with dinosaurs, etc. In the original 1954 GOJIRA (GODZILLA), Professor Yamane theorizes that the monster was trapped in suspended animation and revived by H-bomb tests, but it's only a theory. Some of the natives of Odo Island insist that Godzilla has been around for centuries. At best, the presence of Strontium-90 in Godzilla's footprint can be taken as proof of the bomb connection, but no one knows how long Godzilla was there or where he came from before the atom was split. Steven Spielberg doesn't bother to explain the rather intelligent behavior of the shark in JAWS, beyond the notion that the fish is a rogue who has staked out the waters off Amity for food. If that were true, though, why did the shark stay after the beaches were closed? It's not as though Herman Melville (in his novel) or John Huston (in the film adaptation) ever made any effort to explain why there is a white sperm whale terrorizing the high seas in MOBY DICK, or why it has such a hatred for Captain Ahab. No one knows where the Graboids in the first TREMORS came from, and no one cares. They're there, trying to eat the townsfolk, and that's all that counts. If all of these films (and many more) can not only function, but indeed become major and minor classics of the monster genre, why does CLOVERFIELD have to take a hold of your pudgy little hand and lead you by-the-numbers through the story?
