Civilization Station—machine Age

What is the meaning of life? What is the mission of intelligent life? Where will human civilization go from here? We are just new guests to the current earth. Are we just temporary residents of the earth? What was the earth like before the birth of humans? We still can't make it clear clearly. While technology should be for us to live a better life, its mission should also be to let us know ourselves. But do we really know ourselves? Science fiction is not just for us to satisfy our sense of curiosity that has nowhere to go, but it should also make us reflect on where the future lies.
