This is my favorite ID argument. It's a dishonest catch 22. IDer/Creationist ask for experimental proof, but all such proof involves an experimenter and hence involves a creator/designer so it is tossed out. Of course, the same person who demands proof of scientists is absolutely prepared to accept old myths without any proof
Since when did I ask you for proof on this thread? I commented on your examples. If you had provided an experiment that completely excluded any unnatural advantage introduced by human intelligence, I could not have made the same comment. The fact that plants use simple chemistry to convert sunlight, water, and carbon dioxide into sugars and yeast can then convert these sugars into ethanol does not make that process a likely abiotic event.
Tell you what, put a bass into your bassomatic and blend for five minutes. Then tell me how long it takes for the bass to come back into existence having the entire complement of chemicals required to make a bass.
