Even if evolution had been completley disproven (wich it most defenitly has not been! on the contrary just about evrey expert in the natrual sciences and evrey leading authority in the natrual sciences say it has been proven beyond a shadow of a doubt) and the watchmaker argument was a valid argument it still wouldnt mean anything.
The idea that we, one small group of one species on one planet out of probably hundreds of billions of planets, cirling one star out of BILLIONS of stars, in one galaxy out of BILLIONS of galaxies, in a universe so massive that even if we were to travel at the speed of light for hundreds of millions of years we would not even cross a fraction of it, are the reason this universe is here seems to be an extreme leap of faith.
