Professor's Brain

Pro-science Professor:
"Science says you have five senses you use to identify and observe the world around you.
You have never seen God, Have you? You have never heard God, Have you?
Have you ever felt God, tasted God or smelt God?
In fact,do you have any sensory perception of God whatsoever?

Student:
"Is there anyone in the class who has ever seen the Professor's brain?
Is there anyone here who has ever heard the professor's brain...felt the professor's brain,
touched or smelt the professor's brain?
It appears no-one have any sensory perception of the professor's brain whatsoever.
Well, according to the rules of empirical, stable, demonstrable protocol, science,
I DECLARE that the professor has no brain".
