One day a 6 year old girl was sitting in a classroom.
The teacher was going to explain evolution to the children.

The teacher asked a little boy: Tommy do you see the tree outside?
TOMMY: Yes.

TEACHER: Do you see the grass outside?
TOMMY: Yes.

TEACHER: Go outside and look up and see if you can see the sky.
TOMMY: Okay. (He returned a few minutes later) Yes, I saw the sky.

TEACHER: Did you see God?
TOMMY: No.

TEACHER: That's my point. We can't see God because he isn't there. He doesn't exist.

A little girl spoke up and wanted to ask the boy some questions. The teacher agreed and
the little girl asked the boy: Tommy, do you see the tree outside?
TOMMY: Yes.

LITTLE GIRL: Tommy do you see the grass outside?
TOMMY: Yessssss (getting tired of the questions by this time).

LITTLE GIRL: Did you see the sky?
TOMMY: Yessssss

LITTLE GIRL: Do you see the teacher?
TOMMY: Yes

LITTLE GIRL: Do you see her brain?
TOMMY: No

LITTLE GIRL: Then according to what we were taught today in school, she must not have one!
