The cosmos is full of wonder and mystery

What happens when you read a book [is] stunning. Here’s some product of a tree, little black squiggles on it, you open it up, an inside your head is the voice of someone speaking, who may have been dead 3000 years.
~ Carl Sagan (The Tonight Show with Johnny Carson, May 20th, 1977)

We are the legacy of 15 billion years of cosmic evolution.
~ Carl Sagan (Cosmos: A Personal Voyage, 1990 Update)
