Scuse me, I think you will find the reason the Twin Towers didn't fall over was because of the way they were built. God's hand wasn't 'holding it up'.
the asian Tsunami, horrible as it was was caused due to the effects of tectonic plate movement moving the continents together, my science teacher actually predicted an earthquake before Christmas, and he isn't some kind of prophet.
I don't belive in God at all, I think that many people have easilly been manipluated by the teachings of churches.
And when you die, you don't turn to ash (unless you are cremated..) you rot, your body is absorbed back into the earth (except bone because it dosen't decompose).
