Flower mind is good

You made a mistake again, Professor. 

Just the absence of dark light. 

You can say less light, more light shining light, all these, but we say darkness without any light.

Professor: What do you mean by saying this?

Student: I actually want to reach a conclusion from your philosophy.

Professor: What's the decision?

Student: Sir, you are following the principles of Daily. At the same time, you are arguing for the existence of a good god, bad God. 

Science electricity uses magnetism but they are never seen and rarely felt. Now Professor, you say, do you teach your students that people come from monkeys?

Professor: Of course. 

If you look at biological evolution, then it will admit.

Student: Have you seen this evolution?

(The professor slowly realized where the argument was going.)

Since no one has seen evolution and no one can prove in the laboratory, then do you assume that you are just promoting your faith. Are you a scientist or a preacher?

The whole class suddenly burst into laughter.

Student: Are there anyone in this class who saw the professor's brain?
