A nebulae that was uncounted light-years away came rushing toward them. It was a spinning silver wheel at a distance, but it broke into great blotches of black space to dissolve into just another star system without form or noticeable nebulosity. They swooped over a reddish planet and dropped through its atmosphere. They studied great buildings of stone and metal that towered high into the clouds. Tiny fliers and great air-freighters dotted the skies. The old man said, "This people used their science wisely. They built a civilization that gives every man all he wants which is, in effect, all he can understand." They left the red planet, swept light-years away and down through heavy mists to a greenish globe whirling majestically in the light of its distant sun. Beneath them lush, tropical jungles lifted fronds and branches to the steaming mists. Somewhere in that massed carpet of vegetation an animal screamed in its dying agonies. Through a break in the trees Angus saw a naked man squat and hairy and with a stone-bladed spear in his hand, fleeing before the bounding fury of a gigantic tiger. The great cat was making its last leap, spreading its talons into the man's shivering flesh, as the mists crept up and hid them. "A young world," Stasor said softly, "with all its life ahead of it in which to find its destiny." They went out into space and found a planet where giant insects ruled, where a lumbering thing in the shape of a man, but mindless, was used for heavy labor. Another planet showed lizards dwelling in strangely wrought mansions. A third showed mind-beings that looked like crimson jellyfish hanging in midair by some means of mental suspension. "All these," explained Stasor with a wave of his palm, "are freaks. Life throughout the whole universe, across all of its uncountable light-years, follows mainly a pattern like our own. Creatures that we call man, with two arms, two legs, two eyes, a nose and mouth, breathing atmosphere into lungs, have been the ruling race because of circumstances like gravity and atmosphere, over which they themselves have no control. "One more example, then we're done...." They fled across star galaxies, through sprawling universe where binaries and dwarf stars and red giants alternated against the black void like a spangled curtain. They went through the Megellanic Cluster and the Andromeda nebula. They came swooping down so swiftly that the stars blurred a little, even at their incredible distances, toward another galaxy. Stasor found a little star. It was surrounded by nine planets. He chose the third planet outward from the star, and dropped his observational platform through the heaviside and ionosphere. Angus craned forward. He liked this world. It reminded him vaguely of Karr, with its green grasses and rolling oceans. "Its inhabitants call it the Earth. A peaceful place. Look over there--you can see the city clearer now."
