To illustrate the vain conceit that the universe must be somehow pre-ordained for us, because we are so well-suited to live in it, he [Douglas Adams] mimed a wonderfully funny imitation of a puddle of water, fitting itself snugly into a depression in the ground, the depression uncannily being exactly the same shape as the puddle.

Faith is the lack of evidence, and it shouldn't be that difficult to convince people that the right reason to believe something is that there is evidence for it. People do not innately go for this view, but nevertheless it is not that difficult to teach.

It's a flaw in our argument, for sure. By any reading of evolutionary theory, creationists ought to have died out ages ago. They serve no function in the planet's ecosystem, and no other species has survived so long while in such fundamental disagreement with observable reality. If I wasn't such an ardent believer in secular materialism, I'd wager this is really troubling Darwin in the afterlife.

I am very hostile to religion because it is enormously dominant, especially in American life. And I don't buy the argument that, well, it's harmless. I think it is harmful, partly because I care passionately about what's true.

Religions are not imaginative, not poetic, not soulful. On the contrary, they are parochial, small-minded, niggardly with the human imagination, precisely where science is generous.

We have the power to defy the selfish genes of our birth and, if necessary, the selfish memes of our indoctrination. We can even discuss ways of deliberately cultivating and nurturing pure, disinterested altruism - something that has no place in nature, something that has never existed before in the whole history of the world. We are built as gene machines and cultured as meme machines, but we have the power to turn against our creators. We, alone on earth, can rebel against the tyranny of the selfish replicators.

Creationists are possibly gaining more political power. In the U.S., you are constantly hearing stories of school boards harassing teachers and trying to get textbooks banned.
