Proponents of ID assert that some living structures are so complex that they are explicable only by the agency of an imagined and unspecified 'intelligent designer'. They are free to believe and profess whatever they like. But not being able to imagine or explain how something happened other than by making a leap of faith to supernatural intervention is no basis for any science: that is a theological or philosophical notion.

For a theory to be considered scientific it must be testable – either directly or indirectly – by experiment or observation. The results of such tests should be able to be reproduced by others as a check on their accuracy (and, importantly, if repeated testing falsifies the theory it should be rejected rather than taught as part of the accumulating body of scientific understanding). Finally, a scientific theory should explain more than what is already known: it should be able to predict outcomes in novel situations. Evolution meets all of these criteria but ID meets none of them: it is not science.

We therefore urge all Australian governments and educators not to permit the teaching or promulgation of ID as science. To do so would make a mockery of Australian science teaching and throw open the door of science classes to similarly unscientific world views – be they astrology, spoon-bending, flat-earth cosmology or alien abductions – and crowd out the teaching of real science.
