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: TEACHER : Tommy, do you see the tree outside?
 TOMMY : Yes. 
TEACHER : Tommy, 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 minute 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 : LITTLE GIRL : Tommy, do you see the tree outside?
 TOMMY : Yes. 
LITTLE GIRL : Tommy, do you see the grass outside?
 TOMMY : Yesssssssss (getting tired of the questions by this time). 
LITTLE GIRL : Did you see the sky? 
TOMMY : Yessssssssss. 
LITTLE GIRL : Tommy, 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 in school today…she must not have one!!
