Perhaps worst of all, a majority of these skeptics still subscribe to the myth that science must remain silent about matters of morality and ethics. It is scandalous that so few spokespersons for science have the courage to point out the obvious. The notion of the supernatural is no more intellectually respectable than astrology, precognition, and a host of other superstitious methods of augery. Naturalism is the central working theory of science, and the possibility of the supernatural has by now been reduced to an infinitessimal by evidence more voluminous and decisive than that supporting evolution, relativity, and quantum mechanics combined. Religion, far from being a source of knowledge complementary to that of science, is a collection of myths, miracle stories, and magical promises, promulgating a supposed morality of purely human origins that is falsely attributed to supernatural forces, thus absolving believers from taking responsibility for their own hatreds and prejudices.
Science has no killer demonstration proving that religion and the supernatural are untrue.
But it has amassed mountains of negative evidence, from every avenue of scientific research, demonstrating that supernatural assumptions are not required to explain the world as it is. Such negative evidence is not meaningless, as every successful natural explanation propounded by science makes it less likely that any supernatural explanation will ever be needed. Those who already accept supernatural claims to be absolutely true will never be impressed by such evidence, but those who claim to be scientists cannot ignore it. Neither can scientists ignore the fact that science itself is a moral system. It is trivially true that the findings of science do not imply any moral position.
