Evolution is a theory, and it's a theory that you can test. We've tested evolution in many ways. You can't present good evidence that says evolution is not a fact.

Science is the key to our future, and if you don't believe in science, then you're holding everybody back.

Everyone, red state, blue state, everyone supports space exploration.

Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.

Anybody who grew up with the space program is a fan of science fiction.

We are special in the sense that we can know our place in the cosmos. We can know our place in space. We are at least one of the cosmos's ways of knowing itself. That fills me with reverence and joy. Another insight I really want people to consider is this: everyone has gotten this far. Everyone you meet has made it this far. Nobody is superior to anyone else from an evolutionary standpoint.

The more you find out about the world, the more opportunities there are to laugh at it.
