CAPTAIN SPOCK, Star Trek IV: The Voyage Home (1986)
It began with an act of supreme violence, a big bang, expanding ever outward, cosmos spores of matter and gas, matter and gas, ten billion years ago. Whose idea was this? Who had the audacity for such invention? And the reason? Were we part of that plan, ten billion years ago? Are we born only to die? To be fruitful and muliply and replenish the Earth before giving way to our generations? If there is a beginning, must there be an end? We burn like fires in our time, only to be extinguished, to surrender to the elements' eternal reclaim of matter and gas. Will this all end one day, life no longer passing to life? The Earth left barren like the stars above, like the cosmos? Will the hand that lit the flame let it burn down, let it burn out? Could we too become extinct? Or if this fire of life living inside us is meant to go on, who decides? Who tends the flames?
DANA SCULLY, The X-Files, "Biogenesis" (1999)
Extinction is often the natural end of evolution.
CAPTAIN KATHRYN JANEWAY, Star Trek: Voyager, "Prototype" (1996)
You may wake up one day and find yourself extinct.
DEACON FROST, Blade (1998)
Mammoths can't go extinct, we're the biggest animals on Earth.
MANNY, Ice Age: the Meltdown (2006)
No wonder dinosaurs are extinct: big heads, small brains.
DEVON BUTLER, Cop and 1/2 (1993)
The instant man stops fearing is the instant the species reaches a dead end, only to sink to pitiable lows, only to sit and wait apathetically for extinction. Humans who lose the ability to think become creatures whose existence has no value.
SCHWARZWALD, The Big O (1999)
