Hawkings has ignored all the data concerning cause and effect. He points out the "negatives" of religion but forgets the "negatives" of atheism. He has also ignored the rules of the scientific method. The only way to prove that "heaven" is a fairy tale is to explore every part of this universe as well as alternate realities and realms. Until he has - then he can't claim to make anything more than a religious assertion. That religion is Atheism: where you can only say - "I DON'T BELIEVE THERE IS A SUPREME BEING"- you can't prove there isn't one scientifically. Neither can I prove there is one scientifically, but my basis is faith - and that has different requirements.
In short - the ONLY THING HE CAN SAY AS A SCIENTIST IS: "I DON"T KNOW".
But he doesn't - looks like there is a "prejudice" and "bigotry" there. I don't fault him for it. If I had his illness- I could very well be "bitter". But his obvious errors in making these statements need to be pointed out. He doesn't know what he is talking about.
Now as for the evils of religion versus the purity and morality of atheism:
Take for example - all of the people "murdered" in the name of Marxism- which is an atheistic belief system. You would have more people dead than in all the wars in the last 2000 years: nearly 1/2 billion people.
Then you have charities. Kindly name me one hospital that was established in the "name" of Atheism. Name me one true philanthropist that truly helps people in the name of atheism. All of the hospitals in China were created directly and indirectly by Christian Missionaries. All of the Universities were created directly and indirectly by Christian Missionaries. Name me ONE Atheistic charitable organization -there are NONE (and please don't point out the ACLU or the Red Cross). The Red Cross was started by a Swiss Evangelical - why do you think he used the Cross?
Then there are scientists that are creationists - if you don't believe the list -research it for yourself.

All I would say to Stephen Hawking - God gave you your mind - and and He also gave you your disease - I know that. He could take your life - take your mind - or restore your health - my point is -
In looking at all possibilities - yes you could be utterly rational and brave in facing the unknown.
You also could be a fool. Two possibilities - and eternity in the balance.
