Who's God's Mommy?

Last night Isabella asked me, "Who's God's Mommy?"  I explained to her that God doesn't have a mommy, because he came first, before anyone else.  She declined that explanation because everyone has a mommy...otherwise, how did he get out of someone's belly?  After I tried several stumbling attempts at an explanation, she declared, "It's okay Mommy, I know all about God."  I replied, "That's good, because Mommy is obviously confused!"
