What are the classic quotations from carl sagan's Cosmos?

The classic quotation of carl sagan's Universe is:

1, we are all stardust. It is a great thing that you are still alive at the moment.

2. Without the stability of atoms, we would cease to exist.

Rolling along the Yangtze River, leaving only the past and not knowing the future.

4. The products of stars are thinking about stars, and organisms composed of hundreds of millions of atoms are thinking about the evolution of atoms.

We grew up in loneliness, and the process of self-learning the universe is extremely slow.
