Corrected entry: In the film, a comet always precedes the arrival of the Necromongers, but surely the advanced technology of the future would be able to easily distinguish a comet from giant spaceships.

Correction: If you look at the arriving ships, you will see ice smashing off them from a comet. They are really arriving in and around a comet. Plus it's not meant to be a literal description - everyone knows what it means, so there's no point saying "their arrival is preceded by something that looks exactly like a comet but actually isn't one".
