One day a group of six year olds were sitting in a classroom, and the teacher was explaining evolution to the children.
The teacher asked a little boy: Tommy do you see the tree outside?
TEACHER: Tommy, do you see the grass outside?
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 up there?
TEACHER: That's my point. We can't see God because he isn't there. Possibly he just 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?
LITTLE GIRL: Tommy do you see the grass outside?
LITTLE GIRL: Did you see the sky?
LITTLE GIRL: Tommy, do you see the teacher?
LITTLE GIRL: Do you see her brain?
LITTLE GIRL: Then according to what we were just taught, she possibly may not even have one!
