Corrected entry: How do the "bugs" manage to invade the Earth? Supposedly they hurl meteors through space that land on Earth and cause massive destruction. But the bugs, even though they are huge and intelligent, have no technology. How could they harness the meteor, let alone make sure that it travelled through space accurately enough to hit the Earth?

Correction: There's no way of knowing if the bugs aimed the meteor at Earth, or even if the asteroid came from the bugs at all (and the federation just using it as an excuse to attack the bugs). And it is mentioned earlier in the film that the bugs send their spores through space on asteroids to create new hives. It could very well have been a completely random seeding asteroid that just happened to hit Earth, that was probably laucnhed hundreds of years before the Terran attack.
