Aliens

Definition and stakes

Portrait of Lester Del Rey Lester Del Rey,  The life watch (1954)

“ Nobody had ever seen an Alien—they invariably exploded to dust before they could be captured—but the horror of their senseless brutality was revealed in the hideous human corpses they left behind them.
Norden had been drafted while there was still optimism. Men could build a hundred ships to the Aliens' one, equally radar-proof, free from danger of magnetic or electronic detection, and nearly invisible in space.

Fredric Brown,  Two Timer

“ And now it was sacred ground because the aliens were there too. The aliens, the only other intelligent race in the Galaxy ... cruel, hideous and repulsive monsters.
Contact had been made with them near the center of the Galaxy, after the slow, difficult colonization of a dozen thousand planets; and it had been war at sight; they'd shot without even trying to negotiate, or to make peace.

Portrait of Henry Slesar Henry Slesar,  Beside the golden door (1963)

“ There was never an official estimate of the deaths, but it was certain that well over three thousand of the aliens lost their lives before ever tasting a drop of cool Earth water, or knowing the shade of an Earth tree, the peaceful blue of an Earth sky. ”
