God must live somewhere in the universe, so what's so ridiculous about "near Kolob"?

I don't get why everyone thinks it's so ridiculous that we Mormons believe God lives near a planet named Kolob. I mean, when it comes right down to it, God has to live somewhere. So even if you don't agree with my church, what is so silly about the idea that God lives near a planet with a name you've never heard of? There are billions of planets, you know.
