He'd have to tell the men and women of the crew later, after he'd had time to organize things and present it all in a way they could accept, however much they might hate it at first. But there was no putting off giving the gist of it to Jane.
"It was the blobs," he summarized it. "They seem to be amused by men. They don't require anything from us, but they like us around. Hennessy doesn't know why. They can change our cells, adapt us. Before men came, all life here had twelve legs. Now they're changing that, as we've seen.
"And they don't have to be close to do it. We've all been outside the hull. It doesn't show yet—but we're changed. In another month, Earth food would kill us. We've got to stay here. We'll bury the ships deeper this time, and Earth won't find us. They can't risk trying a colony where three ships vanish, so we'll just disappear. And they'll never know."
Nobody would know. Their children—odd children who matured in eight years—would be primitive savages in three generations. The Earth tools would be useless, impossible for the hands so radically changed. Nothing from the ship would last. Books could never be read by the new eyes. And in time, Earth wouldn't even be a memory to this world.
She was silent a long time, staring out of the port toward what must now be her home. Then she sighed. "You'll need practice, but the others don't know you as well as I do, Bob. I guess we can fix it so they'll believe it all. And it's too late now. But we haven't really been changed yet, have we?"
"No," he admitted. Damn his voice! He'd never been good at lying. "No. They have to touch us. I've been touched, but the rest could go back."
She nodded. He waited for the condemnation, but there was only puzzlement in her face. "Why?"
And then, before he could answer, her own intelligence gave her the same answer he had found for himself. "The spawning ground!"
It was the only thing they could do. Earth needed a place to plant her seed, but no world other than Earth could ever be trusted to preserve that seed for generation after generation. Some worlds already were becoming uncertain.
Here, though, the blobs had adapted men to the alien world instead of men having to adapt the whole planet to their needs. Here, the strange children of man's race could grow, develop and begin the long trek back to civilization. The gadgets would be lost for a time. But perhaps some of the attitudes of civilized man would remain to make the next rise to culture a better one.
