When it comes to science, there are certain criteria for what evidence is. You have to explain WHY it is evidence, and how it fits into the model. One problem with the claims for evidence for Intelligent Design is that there is no mechanism to explain why something is evidence for Intelligent Design. it ends up being on big 'argument from ignorance' or 'argument from probability'.
The evidence has to be explain the model, and it has to be testable .. and explain WHY.
