Meteorite Hits the Earth [Stimulation Only]

There are some questions from me such as

1. What happened to all the evaporated water? I mean there is going to be tons and tons of water in the air in high temperatures. I was thinking of massive hot shower sometime later?

2. How come some fragile structures still stand...Even the Clock rings while Poseidon temple's towers burn red hot!

3. That much of a meteorite would probably crack the earth into two or even push it from the orbit. The meteorite is supposively striking the earth at 700 000km/h and size of the moon...

Answers are welcomed! Overall, its very very good video...Hard to find errors in scientific terms though!
