A long time ago men hunted for their food . Often they killed wild animals , birds or fish . How did they kill the beasts? They used rocks and wooden sticks . Sometimes they fought with their own hands and bodies. Later on , people began fighting each other . Everyone wanted more food and more land . They made arrows from sticks . They also made spears from stones . Then somebody invented the gun.Soldiers were taught how to shoot and kill enemy soldiers . Great was the fight and many people died. A famous general cried as he looked at one battle field . His soldiers were fighting well , but he felt very sad . He turned to his men and said , “My soldiers , I’m going to ask you a question . The one who gives the best answer will receive a medal . The question is this: ‘ What is the strongest power in the world?’ ” Four soldiers raised their hands . They wanted to answer the general’s question . He asked the first one to speak . “Sir!” said the man , “I think my gun is the strongest power . It can kill a person or an animal from a great distance.” “A soldier is strong,” said the second soldier . “He must shoot the gun and aim well . A gun’s power comes from the way it is used .” The third soldier disagreed immediately . “No , sir , our general is the strongest power . He gives the order for his soldiers to shoot their guns” Then the general turned to the last soldier , who answered the question this way . “I believe , sir , that the greatest power on the earth is love . It makes the general decide if he wants his soldiers to use their guns . Also , if men had more love for each other , they would not use their guns.”
