It’s easy to make ideological mistakes in theory. - Liu Cixin

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.

I don’t have much to say except a warning. Life reached an evolutionary milestone when it climbed onto land from the ocean, but those first fish that climbed onto land ceased to be fish. Similarly, when humans truly enter space and are freed from the Earth, they cease to be human. So, to all of you I say this: When you think about heading into outer space without looking back, please reconsider. The cost you must pay is far greater than you could imagine.

Everything you see before you is the result of poverty. But how are things any better in the wealthy countries? They protect their own environments, but then shift the heavily polluting industries to the poorer nations.
