Yeah I would agree.

A comet the size of europe would smash the earth's crust. Every single continent would be on fire and then freeze over from the sunlight being turned off by massive debree clouds all the way into space.

Before that happens, every city would probably experience 8-12 point earthquakes and the crust of the earth would crack into billions of peices like an egg being hit by a bullet.

It would kill all life on earth except airborn bacteria and viruses....those too would eventually burn up from the earth turning into a burning /lava inferno followed by a deep freeze that would probably last 10 years.

It would definately be the end of the world for all humans and animals.
