I don't understand the causation/design argument. Anything complicated enough to create the universe must be just as, if not more, complicated as the universe It creates. If God or The Flying Spaghetti Monster created our universe, then such Entity must be at least as complex as our universe, begging the infinite regress of who created said Entity and why is said Entity so complex? Causation itself is a red herring. The universe is, period, properly viewed in imaginary time, not real time. In imaginary time, it is neither created (caused) or destroyed. It just is. And if you don't understand that, I suggest you re-read 'A brief history of time'. Thus if the universe has no cause then structures within like ourselves should need no Designer, otherwise, who designed the Designer? Design in an un-caused universe ends up being an illusion given to us by natural selection. Within (real) time, natural selection works, creating things like human apes and elephants. Within imaginary time, nothing is created nor destroyed. Natural selection explains design. Imaginary time shows there is no beginning, no need for a cause. Clinging to the god delusion is going to require more than first cause and design arguments boys and girls. There is one sense in which God or The Flying Spaghetti Monster do exist, and that is, they exist as memes. They are viruses which hijack the human mind and in some cases cause the human it hijacks to hijack, say, airplanes. There is a great poster out there with the words, "Imagine no religion" superimposed over a picture of the twin towers. Without God, the meme of God, that is, those towers would still stand. I think its time this species grow up and get rid of the god delusion or else we bloody well deserve to go extinct.
