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

Evolution is not something you can believe in or not believe in like do you believe in gravity.

There is no debate in the scientific community...We need [Congress] to change things, not to deny what's happening.

I've got no problem with anybody's religion. But if you go claiming the Earth is only 10,000 years old, that's just wrong.

Recommending or insisting on abstinence has been completely ineffective.

There are two questions that get to us all: Are we alone in the Universe? And, where did we come from? For me, science provides a much more satisfactory way to seek answers than does any religion I've come across. With that said, the universe is mysterious and wonderful. It fills me with reverence for nature and our place among the stars; our place in space.
