Ladyofthemanor, you said:
'MillyR Surely a theory will forever remain a theory/hypothesis until it is proven. As neither Evolution nor Creation can be "proven" (ie: backed with NEUTRAL evidence, that comes from something OTHER THAN another theory) they both remain up in the air.'
A theory and a hypothesis are not the same thing. Someone else explained this earlier in the thread.
A scientific theory cannot be 'proven' because 'proof' only applies in mathematics, not science.
The theory of evolution is supported by all known currently known facts. If new facts come to be known in the future that do not fit with the theory, then the theory will either be modified or replaced with a better theory that encompasses all facts known now and in the future situation. The same applies to all scientific theories. I'm not sure which theory of gravity is now correct - it is perhaps the third?
Evolution can be demonstrated in the present. Generally what creationists are objecting to is not the fact that evolution is happening now, or even the parts of evolution that they particularly dislike such as speciation are happening now. It would be pretty foolish to try and deny the existence of something that can be observed.
What creationists generally disagree with is that evolution happened in the past. They are then disputing another theory (and one that is far more central to all science, as evolution is only really central to biology) - that is uniformitarianism. That is the theory that the scientific laws that we observe now also existed in the past - gravity, thermodynamics and so. Creationists do not believe in uniformitarianism so can claim that while evolution is happening now, it did not happen in the past.
Creationists can also then deny other scientific ideas that are not connected to evolution - the geological age of the earth for example.
It might also be worth pointing out that a law is more limited in scope and has less explanatory power than a theory. A theory will never become a law; a law explains and predicts a smaller area of science. Some people are confused and seem to think laws are more widely accepted or important or 'true.'
Of course evolution has to include other theories, because the whole of scientific knowledge is made up of theories. As for neutral evidence, as the facts about all biota known to humanity validates evolutionary theory, what other neutral evidence do you require?
You still don't seem to get that for something to be called a scientific theory it has to encompass a massive range of supporting facts, have no existing facts that would disprove it and often encompass a number of accepted scientific laws. It is not the same thing as a hypothesis, which is speculative and may turn out not to fit with any facts when tested.
