One day, in a school classroom, a teacher asks a student a question...
Teacher :"Can you see God?"
Student :"No."
Teacher :"Can you touch God?"
Student :"No."
Teacher :"Then there isn't a god."
Suddenly the student asks the teacher questions...
Student :"Can you see your brain?"
Teacher :"No."
Student :"Can you touch your brain?"
Teacher :"No."
Student. :"Then you don't have a brain?!"
And from that day on, the teacher never asks students that kind of question ever again.
