Watch your Reasoning!

A freshmore in college started his first day of classes. His professor was
clearly an atheist, and started the day by saying the following:


"Students, is there anyone here who can see God? If so, raise your hand.


If there is anyone who can hear God, raise your hand.


If there is anyone who can smell God, raise your hand."


After a short pause, with out any response from the students, he concluded,
"Since nobody can see, smell, or hear God, there isn't any God."


A student then raised his hand and asked if he could address the class. The
student approached the class and asked, "Students, can anyone here see the
professor's brain?


Can anyone hear the professor's brain?


Can anyone smell the professor's brain?"


After a short pause he concluded, "Since no one can see, hear, or smell the
professor's brain, I conclude that he doesn't have a brain!"
