Last night, I took Caedmon to church. It was just he and I. What follows is the exact conversation we had.
*while backing out of the garage*
Caedmon: Oh, look dad, the moon!
Me: Yep, pretty neat.
Caedmon: Are there aliens on the moon?
Me: Nope, there aren't any aliens on the moon. But you know what? A while ago, there were some people who took a spaceship and landed on the moon.
Caedmon: Why'd they do that, dad? To see the aliens?
Me: No, they landed their spaceship on the moon, got out, and drove around and collected rocks.
Caedmon: But they didn't see the aliens.
Me: No, aliens aren't real.
Caedmon: Aliens aren't real? How do you know.
Me: Well, have you ever seen an alien?
Me: Well, there you go. Aliens aren't real.
*some time passes, Caedmon thinks*
Caedmon: Are Pop Tarts real?
Me: *supressing a laugh* Well, have you ever seen a Pop Tart?
Me: Well there you go. Pop Tarts are real.
Caedmon: Cool. So aliens aren't real but Pop Tarts are real.
*pulling up to the church*
Me: Yep. Aliens aren't real, Pop Tarts are real. Do you remember your verse?
Caedmon: "She gave birth to a son."
Me: Good job. See you later.
Apparently, there is a Pop Tart commercial with aliens and the moon? So, I guess in light of that, the conversation makes perfect sense. To my benefit, I just didn't know that at the time.
