My friend Jon Reid relates a story about a conversation that he had with his children while driving them to school, in which his son tells him:
The teacher said we could choose and write that we believed in either creation or evolution. She just said you couldn't believe both.
Jon's response to the questions of his children was perfect:
But the Bible is not a science textbook. Science didn't exist then, we invented science only recently. So it doesn't make sense to put science onto the people who gave us the stories; it's not fair to them. There are questions religion can't answer, and there are questions science can't answer.
I wish there were more parents out there that thought this way.
