Stumped

Jonas stumps me with his questions everyday. I don't even know how he thinks of them. Here were the questions shot at me on the 12 minute drive to school this morning.
How do they build the piers by the oceans?
How big is the ocean?
Where does the Earth end?
How big is Jesus?
What's inside the Earth?
What is the Sun made of? What kind of gas....diesel?
What's magma?
How do the rocks melt?

Now, I consider myself an educated person. I have a degree...in fact, I have a Masters too. And I am a teacher (ok, I teach first grade and those questions just aren't in the curriculum), but he often gets the, "I just don't know that honey, maybe your daddy does" answer.

I do love our conversations and I love the way his brain works.
