The origin of Man

C: Where do cats come from?
Mom: Other cats.
C: But where did the first cat come from?
Mom: Good question! Where did the first person come from?
C: From a fairy who put two people on the Earth, and those people made all the other people.
Mom: Some people think so, but they call the fairy God. Other people think we came from monkeys.
C: No, from apes. First they were apes, then Indians, and then people.
Mom: No, Indians are people. I think you mean Indians were the first people who lived here.
C: The first people to live in houses? No, they didn't live in houses, they lived in pyramids!
