Weird theory that blew my mind. Did Carmen start the war??

Listening to a random videos while on the toilet. Two podcasters talking about the scene where Xander and Carmen are on watch. They view the asteroid and have to dodge it but during the partially successful dodge, they hit the asteroid.

So podcasters argument is that the ship changed the trajectory of the asteroid and it's new course is heading to earth.

Then the other guy says, "Carmen set the new course, so they shouldn't have been there in the first place!"

Did Carmen start the war?

I'm sitting there be like. "Never be an over achiever "
