Out of the Mouths of Babes

My little guy is 5 years old, although he has a vocabulary of an 8 year old. He loves to read and learn new things, so because of that I will call him Professor.
This evening we were driving home from a friends house and had an interesting conversation.
Professor: "Mommy, maybe we are really just a book and someone is reading us"
Me: "Well that would be cool." (as my mind is reeling trying to think of a wise answer)
Professor: "I bet it is a book that will go on forever!"
Me: "Well, ok then." (again, note my deep philosophical answer"
We got home and he started getting ready for bed. When he decided to revive the conversation with this jewel...
Professor: "We are a book, God is the one reading us."
That's my boy!!!
