The Engineer's thoughts were coming again.
"After many years they reached your Sun, and as they approached it they saw that planets were beginning to form around the centers of relatively dense matter. But there was something else. Swinging in a great, erratic orbit on the very edge of this nebula-like mass of raw planetary matter was a planet which they recognized. It was one of the planets of their old home star, fourth out from their Sun. It had been stolen from their Sun, now was swinging in an orbit of its own around its adopted star.
"My people had found a home at last. They descended to the surface of the planet to find that its atmosphere was gone, that all life had vanished, that all signs of civilization had been utterly wiped out.
"But they settled there and tried to rebuild, in part at least, the civilization that was their heritage. But it was a heart-rending task. For years and centuries they watched the slow formation of your solar system, saw the planets take on shape and slowly cool, waiting against the day when the race might occupy them. But the process was too slow. The work of building their civilization anew, the lack of atmosphere, the utter cold of space, were sapping the strength of my people. They foresaw the day when they would perish, when the last one of the race would die. But they planned for the future. They planned very carefully.
"They created us and gave us great ships and sent us out to try to find them new homes, hoping against hope that we would be able to find them a better home before it was too late. For out in space our ships separated, each traveling its own way, bent on a survey of the entire universe if such were necessary.”
"They created you?" asked Gary. "What do you mean? Aren't you direct descendants of that other race, the race of the invading star?”
"No," said the Engineer. "We are robots. But so carefully made, so well endowed with a semblance of life that we cannot be distinguished from authentic life forms. I sometimes think that in all these years we may have become life in all reality. I have thought about it a great deal, have hoped so much that we might in time become something more than mere machines.”
In the silence, Gary wondered why he had not guessed the truth before. It had been there to see. The form, the very actions of the Engineers were mechanistic. Once the Engineer had told them that he was bound by mechanistic precepts, that he and his fellows possessed almost no imagination. And machines, of course, would have no imagination.
But they had seemed so much like people, almost like human beings, that he had thought of them as actual life, but cast in metallic rather than protoplasmic form.
"Well, I'll be damned," said Kingsley.
