As I already stated, you are making no allowance for the information you may be missing. Yes, He only had to say the word to stop it in its tracks. No, we do not know what the consequence of that would have been except to prevent one "natural" disaster.
Flamegrilled, according to you, that information is, at best, a potential unknown graspable unknown. There might be information that we don't know we don't know, and even if we did know that we don't know it, there would be no way understand or use. Because of that, there is no allowance for it because it could never possibly affect any decision we made. There's not even a way to find out if there is some information about this that we don't know we don't know, so it's a complete non-factor.
It's a mystery!
Obviously if you've predetermined an atheistic position and you are just looking for a club to bash theists, then the missing information is just a convenience for now.
No, see what I wrote above. Even if you are a Christian, it only works if God is impotent to the point that he can't solve the superhero's dilemma.
