We Almost Died!!

Yesterday, an asteroid the size of a nine story building almost hit earth. Experts claim the impact would have generated a force equivalent to 10,000 Hiroshima Atomic bombs. The force could destroy an entire continent!(lets hope it's Africa. No one cares about Africa.) 

The question is : how long did they know about this? We had no idea until after the event, so we could have been vaporized instantly without warning. The higher-ups hid it from the world. I would like to know when death is knocking at my door so I know when I can loot and pillage(so much fun!). But more importantly say goodbye to the more meaningful people in my life: however few that may be. The last thing I wanna do is turn into an ash statue on the crapper.
