I appreciated your opinions on the book right up until you scored a howling own-goal by revealing your true thinking: 'Of course they did but they did not have access to the knowledge that we have.'
This is the sort of arrogant thinking that makes much of modern atheistic discussion self-depracating. So many atheists declare that they are scientific, free-thinking and logical, not allowing their personal feelings to cloud their judgement. Yet the number of them that harbour the unwavering belief that theists are ignorant, uneducated sheep, or in the cases of Kepler, Newton and Maxwell simply ignorant of the real facts, is astonishing. A substantial proportion of Christians in the Western world (and no doubt elsewhere - I only speak from personal experience) are educated, free-thinking and rational. You essentially propose that had these three scientists lived today they would have abandoned all outdated notions of a Creator and sided with the enlightened scientists of 2012. But as convenient as this would be for you to believe the world is full of intelligent Christians who are perfectly familiar with modern-day scientific findings yet strangely have not disowned their faith. The sooner this is realised and the topic approached with mutual respect rather than patronising sneers (a la Dawkins) the sooner mutual understanding and tolerance can be achieved.
