Ellie, I think it is foolish to put all our trust the authority of Science and in prominent scientists who, I believe, still have a very incomplete understanding of life and the universe
Who gave you.....smallpox vaccines, aeroplanes, motor cars, the internet, television, telephones, antibiotics, heart transplants, dentistry, computers, anaesthetics, refrigerators, satellite navigation (the list, I'm sure you'll agree, is endless)? Yes, science did. What did religion provide? Sweet FA, unless you count the divisiveness and bloodshed it's promoted for millennia.
You think it's foolish to trust science? Fine. Put your money where your mouth is and pray instead of calling for a paramedic when you have a heart attack or develop sceptemia.
And no, science doesn't know everything and doesn't pretend to, unlike..."Oh, God made the world, because this book of bronze age babble says it did", which is all religion amounts to.
The atheist regimes of the Third Reich and Communist Russia did just that, and were very quick to adopt their own forms of 'Natural Selection' in the last century in order to 'advance human civilisation' (eugenics). Their reasoning was rational and logical, but based on incomplete understanding... and the results were devastating
Seriously? This crap is still being trotted out?
There have never, ever been any atheist regimes on this planet. There have been communist ones - they are not the same thing. That Stalin happened to be an atheist is no more to the point than that he happened not to believe in Father Christmas. Maybe we should call him an asantaist? Look at the harm asantaism has caused in the world 
Oh - and Hitler steadfastly maintained that he was acting in the name of Jesus Christ. That's how he, and others ultimately, justified the holocaust to themselves. Without centuries of Christian anti-semitism it may never have happened.
Of course, Hitler was possibly lying about his beliefs - but that he was not an atheist is without question, I'm afraid. And he knew exactly what to say to the faithful to get him to do his dirty work, didn't he? Remember, Hitler killed no one - he got a lot of Christians to do it for him. Think on that.
You have some reading to do before you attempt to call anyone else foolish.
