So while there are plenty of good books by scientist-atheists, they sometimes under-emphasise the main lesson from science: that our knowledge is vastly outstripped by our ignorance. For me, a life in science prompts awe and exploration over dogmatism.
Given these considerations, I do not call myself an atheist. I don't feel that I have enough data to firmly rule out other interesting possibilities. On the other hand, I do not subscribe to any religion. Traditional religious stories can be beautiful and often crystallise hard-won wisdom - but it is hardly a challenge to poke holes in them. Religious structures are built by humans and brim with all manner of strange human claims - they often reflect cults of personality, xenophobia or mental illness. The holy books of these religions were written millennia ago by people who never had the opportunity to know about DNA, other galaxies, information theory, electricity, the big bang, the big crunch, or even other cultures, literatures or landscapes.
So it seems we know too little to commit to strict atheism, and too much to commit to any religion.
