All that does is insert one more step before the inevitable "I don't know" anyway. After all, if you ask "How is it that there IS a God who has always existed, and why" the answer is going to be I Don't Know."
That said, the only thing about Christmas that makes me cranky is that wretched "Feed the World-Do they know it's Christmas Time" song (I can't even tell if it's all one song or two different ones.) There is nothing like a bunch of millionaires nagging ME to just give whatever I can to feed the world. They live in houses so big that their children get lost in them and a St Bernard has to lead them back, and they're nagging ME to feed the world? The day one of those SOBs lives in a normal sized house because he gave away his fortune to charity is the day I want him preaching to me. Till then, Bah Humbug.
The reason you hate it is because the song isn't honest. It wasn't made to help anything but the sagging careers of those singing it.
Actually that's not true. Part of the beauty of the "God did it" answer is that it is recursively true. Once arrived at the "I don't know" answer is a thing of the past. Clearly you don't know what you're talking about.
