I think the appendix discussion is a little distracting, as again a vestigial organ or gene is the remnant of something that once had more function. I am not sure why you can’t admit that while it may have some function, 11+ million cases of appendicitis say in 2015 with 50,000 deaths is not a good thing! In the US alone we’ve got some 300,000 appendices (plural of appendix lol?) removed each year. A ticking time bomb for many people around the world is yeah, something that may be a leftover from a more useful appendix.
But would you be able to address some of the other questions I had above? It seems that what you believe can falsify the theory of evolution actually tells me that unfortunately you don’t quite understand it-hence why the first article you read on how to falsify had so many disclaimers since many people do not actually understand what they are trying to argue against.
