The most splendid conversation with Sebastian just now.
He walked into my office and asked, "Who Made the Earth?"
"Let me finish this e-mail and then we'll talk." Finish e-mail. "Okay, what's your question again?"
"Who made the Earth?"
So I go over and crouch down beside him. "At the beginning of time there was an explosion [wide-eyed excitement] called the Big Bang. And that created space and time which then began to expand forming the universe and inside [I'm using hand gestures here] there was stuff forming and that stuff came together and built bigger stuff and eventually there were stars and planets."
"Including the Earth?"
"So that's how!" More wide-eyed excitement.
Then I asked, "Where did that question come from? From your brain?"
"I've had that question a long time. Since you got me I've had that question."
OOOO! Cartesian innate ideas?
