The assertion that all scientists believe in evolution is the more dangerous of the two, because of its eternal ramifications: If science has proven evolution beyond the shadow of a doubt, then this universe could have popped into existence without the help of God. In fact, God may not exist at all, according to this line of thinking. And my goodness, if all scientists are in agreement on this thing, we'd be dumb to stick to our outmoded superstitions, wouldn't we?
Ah, but what if there are literally thousands of world-class scientists out there who reject evolution? That would be a different kettle of fish, wouldn't it?
A respected scientist named Dr. Jerry Bergman has put that kettle on display for all to see in his remarkable Slaughter of the Dissidents: The Shocking Truth about Killing the Careers of Darwin Doubters. It's an important book, and I hope you'll check it out soon!
