Not true. If the theory of evolution is supplanted with a better definition to fit the evidence, then evolution will be left on the trash heap of history, along with all of the other discredited theories. No reputable scientist will continue to hang onto a dead theory.
And the creationists will still be there, attacking the theory that replaces it, using the same invalidated arguments, and still with not one shred of evidence to support their position.
They are not the same. Evolution is science. Creation is religion. Science and religion are not the same. How many times has a new study come out, which changes what we thought about the way things work, the theory is changed to accept the new data or discarded altogether in favor of a new theory, and the creationists scream about how science changes. Of course it changes. That is the very nature of science. As we learn something new, it changes our perspective on the workings of the natural world. Science and religion are not the same.
If you are an educator how would you handle a creationist student? Would you just write him/her off as a lost cause as you have done in your post?
