Your post reminds me of a silly anecdote from about a year ago:

I was helping teach a Sunday school class full of four and five year olds, and on the first day of school we were teaching them about the Creation stories. After telling them about all the things God had created on each day of creation, one precocious youngster raised her hand and asked, "If God created all that, who created God?" We all kind of looked down at our feet and told her to ask her parents. It's very rare to find an adult who thinks they have an answer to that question, but since that little girl started asking those questions at age four I'm positive she's on her way to becoming a great philosopher.
