Everybody is an atheist in saying that there is a god - from Ra to Shiva - in which he does not believe. All that the serious and objective atheist does is to take the next step and to say that there is just one more god to disbelieve in.

There does seem to be a sense in which physics has gone beyond what human intuition can understand. We shouldn't be too surprised about that because we're evolved to understand things that move at a medium pace at a medium scale. We can't cope with the very tiny scale of quantum physics or the very large scale of relativity.

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.

The take-home message is that we should blame religion itself, not religious extremism - as though that were some kind of terrible perversion of real, decent religion.

The recurrent laryngeal nerve - which runs from the head to the voice box - goes all the way down into the chest, loops around a major artery, then goes all the way back up again. It goes right past the larynx on the way down. All a decent designer would have to do is loop it off at that point. What we're looking at is the legacy of history.
