this may be a possible real life story a day to end all 
days fire ash a tsunami a rock may be the end the end of 
all civilization man defeated by nature the facts are all 
there but no one even cares a rock may be the end the end 
it is very possible that a comet or an asteroid may hit 
the earth at any time. if that did happen, and the rock 
was big enough, it would first kill all civilization it 
hits and in time the ash and dust etc... would kill the 
rest of the world. if by chance the rock hit water 
instead of land it would be even more devestating with 
tsunamis drowning the earth. most people think that we 
have plenty of people watching out for them, but in 
reality we dont. the government would rather spend their 
money on other needs like weapons etc...
