And then blank astonishment sank home in me—astonishment at the last two words of her remark. I was already familiar with the Zens' enormous intelligence, knowing Yurt as I did ... but imagine thinking to qualify years with my when just out of nowhere a visitor from another planetary orbit pops up! And there had been no special stress given the distinction, just clear, precise thinking, like Yurt's.

I added, still a little awed: "We know how long ago your world died."

"I was child then," she said, "I don't know—what happened. I have wondered." She looked up at my steel-and-glass face; I must have seemed like a giant. Well, I suppose I was. "This—what we are on—was part of Sorn, I know. Was it—" She fumbled for a word—"was it atom explosion?"

I told her how Sorn had gotten careless with its hydrogen atoms and had blown itself over half of creation. (This the E.T.I. Teams had surmised from scientific records found on Eros, as well as from geophysical evidence scattered throughout the other bodies.)

"I was child," she said again after a moment. "But I remember—I remember things different from this. Air ... heat ... light ... how do I live here?"

Again I felt amazement at its intelligence; (and it suddenly occurred to me that astronomy and nuclear physics must have been taught in Sorn's "elementary schools"—else that my years and atom explosion would have been all but impossible). And now this old, old creature, remembering back three thousand years to childhood—probably to those "elementary schools"—remembering, and defining the differences in environment between then and now; and more, wondering at its existence in the different now

And then I got my own thinking straightened out. I recalled some of the things we had learned about the Zen.

Their average lifespan had been 12,000 years or a little over. So the Zen before me was, by our standards, about twenty-five years old. Nothing at all strange about remembering, when you are twenty-five, the things that happened to you when you were seven ...

But the Zen's question, even my rationalization of my reaction to it, had given me a chill. Here was no cuddly teddy bear.

This creature had been born before Christ!
