Is there a God?

One day a 9 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:
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 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:
Yesssss (getting tired of the questions this time).

Little girl:
Did you see the sky?

Tommy:
Yesssss ...

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 today in class,
she must not have one!
