You keep banging on and on and on and on ...about "arguing from authority", pete, but isn't that exactly what you are doing? After all, don't you rely on quoting from creationist 'scientists' who you believe to be 'experts'? And don't you rely on (on what you believe to be) the authority of the Bible? Or have I got it all wrong? Do you, in fact, spend lots of time in the field painstakingly examining fossil beds and their stratigraphy? Or do you spend your time in the lab subjecting interesting samples to a variety of dating methods or following fruit flies or bacteria through many, many generations. If, though, you're not a 'hands-on' practical scientist, then, surely, you're 'merely' arguing from authority and, presumably, we can ignore everything you say ... have I got that right, pete?
