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.

In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe

Our loyalties are to the species and the planet. We speak for Earth. Our obligation to survive is owed not just to ourselves but also to that Cosmos, ancient and vast, from which we spring.

What's the harm of a little mystification? It sure beats boring statistical analyses.

Science is a way of thinking that helps you not to fool yourself.
