"Well, if you ask me, the ergonomics are all wrong for these things to have been designed for us," said Miller. "Whoever made this stuff probably wasn't human." Weyland pulled the mask away from his face. "Spare us your science fictional explanations, Dr. Miller." Suddenly Miller's PC beeped and he studied the readout.

"There are two chemicals here. Tilanium and cadmium 240."

"Never heard of them," said Sebastian.

"They're found in meteorites."  "Meteorites?" Sebastian cried. Miller smiled in triumph. "Whatever these are, they weren't made here."
"When you say 'here,' you mean ... ?" Weyland's
voice trailed away. "I mean Earth," said Miller.-Chpt.19 pg.163

"I don't know about that," Sebastian replied. "But
the one thing I do know for sure-" He pointed to the weapon cradled in Weyland's hands. "Five thousand years ago our ancestors were killing one another with wooden clubs and knives chipped from obsidian. Not these things."

"So little green men may not be so wide off the
mark," said Miller from the sidelines. He was rechecking the readings on his spectrometer after a thorough examination of another of the Predator weapons. "I've just completed a basic spectral analysis of the metal. The majority of the compounds here are simply unknown, but the two elements I can place we've met before-tilanium and cadmium 240." Miller closed the cover on his spectrometer. "Well, whatever it is, we're not prepared for it," Lex said. She stared down the long, dark corridor that had opened up behind Weyland.-Chpt.20 pg.170
