"I don't mind admitting I'm scared, Doctor," Brent Taber said.

"I think it's a time to be scared."

"But if a race of people were that advanced, if their intention is hostile, why do they pussyfoot around this way? Why don't they just come down and take us over?"

"I've wondered that, too. And yet, a race on some planet out there in the universe might not evolve according to what we consider a logical pattern."

"What do you mean?"

"I mean that while they can create a synthetic man, their interests, and therefore their progress, may have stayed in peaceful channels. For instance, they may not have bothered with anything as elementary as the atom bomb."

"It's a thought."

"A wishful thought, I'll admit. But it does have some validity. Also, it has a fact of some possible value to back it up."

"What fact?"

"That they haven't come down and taken us over."
