I don't believe it, but it could also be the case that the God is wiser than everybody praying for their monarch to have an unnaturally long life, and knows that monarchs dying in a regular sort of way is best for the kingdom.
I'm an atheist, but many of the arguments put forth by atheists seem very lame to me.
That is what people seem to believe, coherent or not. I think you will find few Christians who believe their god is just some sort of mechanism to be commanded as they please.
If you want to persuade them to believe otherwise, then you have to come up with arguments which are actually persuasive from their perspective. This is a problem I see with a lot of smug atheist literature. It's also a problem I see with all the arguments from Christians about why I shouldn't be an atheist. I guess I seem approachable to them, I get a lot of well meant but totally fruitless conversion attempts. They are arguments which doubtlessly seem very sound to them, one who already believes, but totally fall flat to me, somebody who doesn't. Like telling me how many different people claimed to witness Jesus resurrection... that seems like compelling evidence if you already believe that the bible is reliable. Christians tell each other these arguments at Church, find it very convincing because they are already convinced and find it hard to imagine the frame of mind of somebody who doesn't believe, then with great earnestness present these arguments to nonbelievers and are puzzled when it doesn't work.
Well that's exactly what's going to happen when you confront most Christians with "Your god isn't real because he doesn't do as you command him to with your prayers." Prayer failing any empirical test of efficacy is convincing evidence to people who already don't believe but totally falls flat with people who do.
