Ever since the Reformation, there's a sense in which the road to atheism was paved not with science, but with religious intentions. - Jonathan Miller

There is one aspect of our own mentality for which it's difficult as yet to foresee what type of explanation would even be relevant. I'm referring, of course, to consciousness. The point is that although I have no reason to believe that my consciousness is implemented by anything other than my brain, I remain convinced that there's something impenetrably mysterious about the relationship between brains and thoughts. And you can understand, therefore, why it's so hard to imagine, let alone tolerate, the idea that the death of the brain necessarily leads to the end of the personal self—and this, of course, is the "trump card" with which religion has consistently played.

Paradoxically, some of the sources of disbelief are to be found amongst the arguments of believers. … Theologians often formulated the most dangerously skeptical arguments in their efforts to test the impregnability of their own faith, and in doing so, they unknowingly furnished atheists with ready-made weapons.

There were academics and theologians who spent hours calculating what they thought was the precise age of the Earth, on the basis of the Biblical account of it. And as early as 1650, James Ussher had come to the startlingly precise conclusion that the Earth was created in 4004 <small>B.C.</small> on October the 22nd—in the evening, apparently. What God had been doing that morning is still open to conjecture.
