You are all missing something. First, it is not necessary the asteroid to hit Earth. It is enough to pass very close to cause dramatic change to the environment. Second, if it hits Earth, it will take some time for us all to die. Only those who are directly hit will die immediately. The rest will suffer much longer. And last, this agency may not have the means to stop a potential danger from space indeed. Not yet...but its existence and the work these people are doing is the first step to a bigger defense. It is true that the world did not end until now even though there was no such institution. But is it bad that it now exists? Every opportunity to increase our chance to survive is worth the efforts.
