My best theory about the world, constructed on the basis of experience, gives me pretty good reason to believe that well-prepared dinners have a human cook. There are a number of reasons why it doesn't necessarily follow that this universe must have had an intelligent creator. The disanalogies are pretty obvious, really. And the theory of evolution by natural selection plays an important role in helping us to understand how ecosystems could have come about from the operation of physical law without the intervention of any intelligence.
Suppose we grant Anselm the premise that we can conceive of a maximally perfect being and also that existence is a perfection. It's still clearly a logical fallacy to infer from the conjunction of those two that a maximally perfect being actually exists. It's a bit of a mystery why smart people put so much effort into thinking about this.
Going to your link, the bit about the beauty and majesty of creation is basically just an expression of incredulity about the idea that it could possibly exist without an intelligent creator. This shouldn't really carry any weight with anyone.
So yes, Dostoevsky said "If God does not exist, then everything is permitted". But you see this isn't really true. Quite obviously, even if God does not exist, there are certain things that the legal system does not permit me to do, certain things that my wife does not permit me to do, and certain things that I would end up having a bad conscience if I did. Sure, you can always just do whatever is physically possible if you choose to as long as you're willing to not worry about consequences and also put aside any kind of moral qualms. But that's obviously the case, for the duration of your time on earth at least, whether there's a God or not. So really, how can you make any sense of Dostoevsky's remark? Or, as one might put it, if it's true that if there is no God then everything is permitted, then what difference does it make if we bring God into the picture? How could it *not* be true that everything is permitted? If God will punish those who defy his commands, then okay, if that were so then that would be part of the reality you face, just as one might say that when Winston Smith lived in the totalitarian regime of the novel "1984" the inevitability of the consequences of his rebellion against the Party was part of the reality that he faced too. But I mean, what's that got to do with anything? Is it some kind of point about meta-ethics?
"Atheism offers no standard of right or wrong, of truth or falsehood, and provides no answers to the questions of the searching heart."
Actually, the atheist has just as many resources to offer such things as the theist does. If you find that the answers on offer provided by atheists don't satisfy you for one reason or another, well I mean there it is, that's a problem you have. But you should equally acknowledge that some people are not satisfied with the answers provided by religion either because they find that their reason doesn't permit them to seriously entertain the idea that the teachings are true. So where's the asymmetry here?
"A belief in God alone answers the centuries-old questions of existence: “Who am I? Where did I come from and where do I go after I die?” "
An atheistic naturalistic outlook informed by our best science answers those questions too. It's just that you have this hang-up that you feel as though it would be a bit depressing to have to accept these answers.
All that this really amounts to is him confessing that he doesn't feel he has the resources to cope with getting through life without using theistic belief as a crutch. Some of us have what it takes to face reality.
