this old woman, who had weathered so many storms and become as gentle as water, - Liu Cixin

If the entire history of the Earth were condensed into a single day, one hour would equate to 200 million years, one minute to 3.3 million years and one second to 55,000 years. Life would appear as early as eight or nine o'clock in the morning, but human civilisation would not emerge
until the last tenth of the last second of the day. From the morning that philosophers held the first ever debate on the steps of a temple in Ancient Greece... from the day slaves laid the first foundation stone of the Great Pyramid…… from the minute that Confucius welcomed his first disciple into the candlelit gloom of his thatched hut... right up until the moment you turned the first page of this book, only one tenth of the tick of the clock would have elapsed.

I want to tell all those who believe in God that I am not the Chosen One. I also want to tell all the atheists that I am not a history-maker. I am but an ordinary person. Unfortunately, I have not been able to walk the ordinary person's path. My path is, in reality, the journey of a civilization.

We extend our best wishes to you, inhabitants of another world.

After reading the following message, you should have a basic understanding of civilization on Earth. By dint of long toil and creativity, the human race has built a splendid civilization, blossoming with a multitude of diverse cultures. We have also begun to understand the laws governing the natural world and the development of human societies. We cherish all that we have accomplished.

But our world is still flawed. Hate exists, as does prejudice and war. Because of conflicts between the forces of production and the relations of production, wealth distribution is extremely uneven, and large portions of humanity live in poverty and misery.

Human societies are working hard to resolve the difficulties and problems they face, striving to create a better future for Earth civilization.The country that sent this message is engaged in this effort. We are dedicated to building an ideal society, where the labor and value of every member of the human race are fully respected, where everyone's material and spiritual needs are fully met, so that civilization on Earth may become more perfect.

With the best of intentions, we look forward to establishing contact with other civilized societies in the universe. We look forward to working together with you to build a better life in this vast universe.
