From time to time we've talked about the argument for an intelligent designer of the universe based on cosmic fine-tuning (okay, maybe a little more often than just "from time to time"). Anyway, here's a four minute video by Justin Brierly on the subject that serves as a nice primer for those not wishing to get too bogged down in technical aspects of the argument: Brierly is the host of the weekly British radio show Unbelievable which is available on podcast. Each week Justin brings together believers and unbelievers to talk about some issue related to matters of faith. The discussions are almost always pleasant, informative, and Justin does an excellent job moderating them. They're usually what such conversations should be like, but too often aren't.
If you'd like to sign up for the podcast or browse the archives of past shows which have featured discussions on almost every topic related to religious belief you can go to the Unbelievable website here.
For those readers who might prefer a slightly more elaborate explication try this post and the debate it links to.
