The evolutionary explanation for origins, although impossible either to prove or to test scientifically, is nevertheless defended by its proponents on the basis that it is the only explanation which is naturalistic, not involving the 'supernatural' element of a divine Creator.

It is impossible to devise a scientific experiment to describe the creation process, or even to ascertain whether such a process can take place. The Creator does not create at the whim of a scientist.

When I was a young girl, I was so crazy about animals that I wanted to do something associated with them, and I thought of being a vet. But then again, I figured I had to go to medical school, and science wasn't a good subject for me, so I dropped the idea pretty soon and thought maybe I could be a vet's assistant.

I don't think Brian Cox does 'The Wonders of the Solar System' because he believes the world would be a better place if people understood about the rings of Saturn; I just think he finds physics extremely interesting. It brings him joy, and he wants to spread the love. I feel the same about economics.

Most people have no concept of how an automatic transmission works, yet they know how to drive a car. You don't have to study physics to understand the laws of motion to drive a car. You don't have to understand any of this stuff to use Macintosh.
