He is alarmingly certain:

If I were a scientist, I'd stick to the Goldman Sachs principle: bet on both sides.

"Believe in science, believe in God" seems to cover all the possibilities and gives you the best chance for a cheery afterlife.

For a time, it was thought that astrophysicist Stephen Hawking had also left a tiny gap in his credo window for a magical deity. However, he has now come out and declared that there is no God.

He gave an interview to Spain's El Mundo in which he expressed his firm belief that el mundo was the work of scientifically explainable phenomena, not of a supreme being.

Hawking said: "Before we understand science, it is natural to believe that God created the universe. But now science offers a more convincing explanation."

I'm not sure whether there was a specific moment in which science overtook the deistic explanation of existence. However, El Mundo pressed him on the suggestion in "A Brief History of Time" that a unifying theory of science would help mankind "know the mind of God."

Hawking now explained: "What I meant by 'we would know the mind of God' is, we would know everything that God would know, if there were a God. Which there isn't. I'm an atheist."

He added: "Religion believes in miracles, but these aren't compatible with science."
