What exactly is ID?

What it means is that ID makes no prediction as to the pattern of homology in living species or in the fossil record. Evolution does make a prediction. You still need to address how many hotspots there are (hint: 1.5 billion).You also need to address Fig. 1 in this paper which shows thousands and thousands of retroviral insertions that occurred in every chromosome and at different bases. Also, you need to discuss how mutational hotspots can explain LTR divergence and overall ERV divergence. You also need to explain how insertional hotspots can produce a nested hierarchy. The question is what evidence, if found, would falsify ID?

Two mistakes. First, you are pointing to organisms that are products of over 3 billion years of evolution as "the simplest forms of life". Obviously, that is seriously wrong. The simplest forms of life would have been the first life, not the life that is at the 3 billion year end of a natural process that produces information in genomes (i.e. evolution).Second, you never offer evidence of a designer. Instead, we just get an open ended question. That really doesn't help much. If encyclopedias reproduced and did so imperfectly while being subject to natural selection, no I wouldn't believe you. Perhaps that's because manmade machines did not evolve. They face hostility because they dissent from the theory of evolution because of their religious beliefs, not because of the evidence. That hostility is well earned.
