Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.
After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.
Our ancestors worshipped the Sun, and they were not that foolish. It makes sense to revere the Sun and the stars, for we are their children.
Human beings have a demonstrated talent for self-deception when their emotions are stirred.
The cosmos is within us. We are made of star stuff
We began as wanderers, and we are wanderers still.
Anything else you're interested in is not going to happen if you can't breathe the air and drink the water. Don't sit this one out. Do something. You are by accident of fate alive at an absolutely critical moment in the history of our planet.
In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist's signature.
