In the class, a university professor asked one of his students :" Does God create everything?"

The student answered bravely :" Yes, he creates everything."

" Does God create every things? " The professor asked again.

"Yes, sir." The student answered.

”The professor continued to ask:" If God create everything, does evil also created by God? According to the main actions of human beings, is God evil?"

The student was in silence and couldn't reply.

The professor seemed to be complacent and he thought he has proved again to the students that religious belief is just some unreal mythologies.

At this moment, another student raised his hand and said:" Professor, may I ask a question?"

"Sure." The professor said racily.

The student stood up and asked:" Professor, does cold exist?"

"What's your meaning? Cold do exist, don't you feel it?" The professor answered and other students all brusted into laughter.

The student retorted:" Sir, in fact cold does not exist! According to the elements of physics, the cold we feel substantially is just lack of heat. When the heat exists or the energy transmits, we can feel it. The heat can be measured, but the cold can't. The word cold is just for us to describe the feelings when we are lack of heat. The absolute zero(273 degrees below zero) is the complete obiteration of heat and alll things stop motion, including all the category, such as molecules, atoms and so on. But this is the absolute phenomena. In fact, there is no absolute zero."

The student asked again:" Professor, does dark exist?"

The professor answered:" Absolutely exist."

The student said:" You are wrong again. Dark don't exist, either! Actually, dark is the result of lack of light. Light can be measured while dark can not. We can use Newton's prism to decompose sunlight into its various colors and we can research their respective wavelength. But dark cannot be measured. Just a flash of light can split the dark world and bright it. Whereas, you can not know there is  how much dark in a certain space. So the word dark is just for human to describe what it is like when there is no light."

At last, the student asked:" Professor, does evil exist?"

Then the professor said with unsureness:" Absolutely, I have said that we can see evil everyday. Everyday human have the act of cruelty and there are evil and violent human beings all around the world. What else can it be except evil?"

Then the student said:" Professor, you are still wrong. there is no evil! Evil is the state without love in the heart. It is the same as cold and dark. Evil is the word for human to describe the state lack of love. God doesn't creat evil but love. Only when human eat the forbidden fruit, love in the heart is becoming less and less. Evil is the result for human lack of God's love in the heart. As the coming of cold is because of the lack of  heat and the coming of dark is because of the lack of light."

Then, the professor asked:" Young man, what's your name?"

The student answered:" My name is Albert Einstein."
