You wrote: "Ask science again "what is 'natural?'" and all it can say is "whatever can be known by science or is not "supernatural." Talk about low standards for precision. Talk about circular reasoning. Most of all talk about presuppositions and biases. And this from a pursuit that is by its very nature dedicated to true knowledge."

I am curious about what you mean by "true knowledege". If one observes that X-rays behave in such and such fashion, as observed by scientists (physicists, chemists, radiologists), where is the place for "an intelligent deisgner"? X-rays are not mentioned even once in the Bible. They seem to be naturalistic in origin. Do you have an objection to how X-rays behave?
Could you say where the understanding of X-rays is "circular reasoning"?
First, human intelligence took the raw materials and, assembled the technology and substance needed to make X-rays. Second, although unseen, all the particles necessary to complete this process and make it repeatable have remained organized and consistent so as to make the application of human intelligence possible.
The fact that X-rays themselves are not mentioned in the Bible has no bearing on whether or not they are intelligently designed. When the Bible speaks of intelligent design as related to the things science has to work with, it denotes all the substance and processes science has heretofore been able to indentify, plus many things science has yet to identify.
