dinosaurs

Evie's fascinated with dinosaurs.  Here's a conversation we had when I was putting her to bed one night:

Evie: What happened to the dinosaurs?
Me: They all died.
Evie: Why?
Me: I don't know, they just died.
Evie: Where are they now?
Me: Well, their bones are buried in the ground.
Evie: How did they get there?
Me: They just got there.  You see, the dinosaurs all died and over time the dirt covered their bones.  So that's how they got in the ground.
Evie: But who put them there?
Me: No one put them there.  They're just there.
Evie: Did people put them there?
Me: No, no one put them there.
Evie: But how did they get in the ground?
Me: Good night Evie.
