Chickens and eggs

Breakfast discussion this morning ...

Me: "Which came first, the chicken or the egg?"

Child No.1: "The chicken."

Me: "But how was the chicken born? Didn't it have to come from an egg?"

Child No.1: "No."

Me: "Why not?"

Child No.1: "Because dinosaurs made the chicken."

Me: "But don't dinosaurs have eggs."

Child No.1: "They don't have chicken eggs, they have dinosaur eggs and those are buried in the ground."

I withdrew at that point. This debate has clearly been resolved.
