I have to admit I stopped reading this thread because it's said the same thing in different ways over and over.
I came across this nice review, thought of making a new thread but well, it fits much more nicely here:
http://www.newscientist.com/article/...ut-design.html
Read the comments that follow. I always find them fun and informative, more or less extending the scope of the article they correspond to.
And for those who don't have the motivation to read, the nice review is about a book that discusses how life exists without the need for a "designer".
