You're right because as soon as a contradiction is found, the theory changes. Thus, the theory can never be wrong because it is, by definition, always right. Some say that's how science always works but that's not true. Theories are dumped all the time when facts turn up to contradict them.It doesn't contradict my Christian beliefs if we really did evolve from protozoa. The Bible says much about WHO created us but little about HOW he created us. However, as a scientist, I find some of the claims of evolution as it taught today to be tenuous. Many scientists much smarter than I am have problems, too.
Unfortunately, the history of the theory of evolution has more flip-flops than John Kerry.
