How did the Earth form? What was the rotation pattern of the sun, moon, and stars? Were there other lifeforms like them beyond the horizon?

Even in the darkest era, there would always be people who held expectations for the future and worked hard until the last moment. Even if things could not be done in the end, they could still say without regrets, "We no longer have any regrets."
"There are still many things we haven't understood, and we haven't seen the origin and end of the universe. Fighting out of the cold era hasn't made us forget our initial motivation."
