What is your favorite book about the end of the world?
Or your favorite movie?
I love Edgar Rice Burroughs. Best known for his Tarzan books, he also wrote about the discovery of life on other planets - sometimes because our own planet was facing extinction.
And my favorite movie about the end of the world (which also didn't happen, thanks to some terrific heros) is Independence Day. I especially love the line Will Smith shouts when he flies the alien spacecraft for the first time: "I have GOT to get me one of these!"
