The irony of the 'god is dead' crowd is that you have to believe in god in the first place for god to die. Now if you don't believe god exists, that he/she/it is a manifestation of the minds of men trying to explain the mysteries of the natural world, that's another matter. Or maybe they believe that god is really some extraterrestrial with such awesome powers that the populace was amazed/terrorized at their fiery appearance, coming down through our planet's atmosphere. If you were to pluck someone from a technological society like today's US, complete with all their electronic gadgets and other tech marvels and placed them down squarely in ancient Athens' agora they, too, would be viewed as gods. Even a Bic lighter going back in time to the caveman days would be incontrovertible truth of the power of the person with that lighter. Man, when confronted with things he does not understand, has an imaginative mind with the ability to plug such knowledge holes with a soothing and comfortable belief in a god or gods, monotheism being of relatively recent origin.
Heron of Alexandria was the first person to make technology available for use by the religious priests of his day. He even invented the coin operated holy water dispenser, it being a mystery to the faithful how a coin inserted into a slot produced a cupful of water, thereby 'proving' the power of the priests. Nothing like selling a little overpriced water to make some scratch, a 'transformation' which could be viewed as real alchemy. Until Copernicus was able to prove the earth revolved around the sun, earth was the center of the universe and heretics were killed who disputed that known 'fact'. As more and more knowledge is revealed through science, some mysteries of the world disappear (lightening, earthquakes, giant fossil bones, planetary orbits, comets, etc.) only to be replaced by other and newer unexplained phenomena (dark matter being just one example).
Religion has always been about power, about control, even about wealth. Religion has helped order man's societies for millenia, and that's not a bad thing. Then along came islam, a religion which is the perfect summation of power, control and wealth, along with a 'scriptural' rejection of science itself.
I'm a firm believer in the 'god is a product of man's imagination in order to explain the natural world' theory. Just because we don't understand things happening in our universe doesn't mean there is a god responsible for them.
