Ancient Greek mythology divided human society into five eras. The first era was the golden age. It was the time when kronos, the God of Time, ruled the world. People in this era live as carefree as God and don't need to work. They will never be old, their hands and feet will always be strong, they will not have diseases, and they will live a happy life by eating, drinking and having fun. They lived for a long time before death came. This death is like a quiet sleep. They were all rich when they were born, and the earth automatically provided them with rich fruits. People live a comfortable life without disputes, and God himself will come to discuss things with them. The golden age is over, and no one survived in this era. After their death, they become ghosts and protectors of future generations of mankind. Justice, punishing evil and promoting good were rewarded by Zeus, the king of the gods. The golden age has passed and mankind has entered the silver age. People in this era are not as happy as those in the golden age. They stayed at home for a hundred years, but they were still unreasonable. Once they grow up, they will leave their mother at once. Adults' life span is short, because they are not smart enough, so they will encounter many misfortunes and pains in life.

People in the silver age didn't obey the rules. They don't obey the eternal God and don't want to burn incense and sacrifice for God on the altar. Zeus wanted to destroy this generation and send them to the dark underground kingdom. They live there without joy or sadness, but they are still respected by future generations. The third era created by the gods is the Bronze Age, and the characteristics of people in this era are powerful and terrible. They were created by Zeus with a spear.

People in the Bronze Age were arrogant and loved wars full of pain and groans. They don't grow or eat food that grows in orchards and farmland on the earth. Zeus gave them tall bodies and indestructible strength. Their hearts beat so hard that they couldn't stop, and their hands couldn't be subdued. Their weapons and houses are all made of bronze. People in the Bronze Age killed each other, and their lives soon disappeared, and they entered the ghost domain of Hades and bid farewell to the light forever. After the Bronze Age, Zeus created a heroic age. People in this era live on the earth, have noble and just personalities, and are demigod heroes similar to gods. They all died in the cruel war first. Some things died in the struggle for the inheritance of king Oedipus, and fell under the seven-door city of Tebai, while others died in the famous Trojan War. All the demigod heroes were taken away by death, and Zeus sent them to the ends of the earth far from the living. They live a happy and carefree life in the blissful island in the turbulent Yanghe River. The fertile land there provides them with dried fruits as sweet as honey three times a year. The previous generation lived in the Black Iron Age, and people in this era have been on the earth until today. People are suffering from sadness and heavy work day and night. The gods also bring pain and trouble to mankind. Among them, the gods also participated in doing good in doing evil, but they did more evil. There is pain everywhere.

This generation has no respect for their parents, their friends are unfaithful to each other, their masters are not hospitable, and their brothers are not loving each other. This generation is morally corrupt, does not keep their vows, does not advocate justice and kindness, hates each other, and is full of violence everywhere. People only see honor and strength. The goddess of conscience and justice has bid farewell to mankind. They returned to the middle of the gods on Olympus, leaving a heavy disaster for mankind, and mankind has no resistance to these disasters. Thank you ~ ~ I hope to help you! ~
