Is comet Elenin a spaceship?

Sorcha Faal says the comet has a controlled orbit. NASA cannot guarantee the comet will miss the Earth. But if we see the official numbers, the comet will pass pretty far from Earth. How then NASA cannot guarantee? Either they hide real data, and that is very distrubing because it means they know the comet comes towards us, to say ever such a thing, or...
it is true the comet is directed by someone. Or it is a spaceship disguised as a comet. Similarly, Alex Collier said about the comet Hale-Bopp to be Orion spaceship. If it is a spaceship, then we might have an alien invasion instead of impact. As we are already warned by the movies. The rapture ET force wouldn't use such tricks. The reptilians will because according to Alex Collier they are H-based and cannot travel faster than light. Therefore slower objects like comets and asteroids are ideal for them to travel, unseen by anyone.
