Every time I have the discussion with anyone that believes in any kind of creationist principles I have exactly the same discussion, the vast majority of these people have no understanding of the basic principles of science, do not understand things like what is a hypothesis, what is a theory, and most importantly what is evidence.
The argument is always circular, as they either, choose to ignore what you say, or chose to use the 'god of the gaps' arguments to try to throw the discussion of kilter.
Reality, trying to discuss anything with someone who has swallowed creationist dogma is boring, defacto, creationists are boring people who do not want or wish to find out what new things have been discovered about the world in which they live, but seem happy to accept and use any modern technology that science and the theories of science have brought them, funny how they all use the science, but decry the validity of research.
