I think I’m going to do one, maybe two more posts in the “Skeptics Answered” series.
Near the end of the comments section in the Call to Skeptics, Muse 142 states:
I find the Ultimate 747 argument to be particularly compelling. In essence, god is a bad explanation for [whatever] because the existence of such a complex, powerful, and intelligent entity such as a god is very highly improbable. (In other words, if you think that cellular life is too complex to “just have happened”, wouldn’t God be infinitely much more so?)
I’m going to be lazy on this one, for its been taken care of in other places by other guys that are much more erudite than I.
So, go here and here. In the second link, you must scroll down about half way to get to Dawkins’ “Ultimate 747″ argument.
They pretty much take care of the issue.
