Theory vs Theory
When ignorant creationists, such as Ronald Reagan, taunt evolutionists by saying Its only a theory they are pretending not to understand that theory to a scientist does not mean hunch as it does in informal English. It means theory in the sense of music theory, the theory of gravity, the germ theory of disease, cell theory, theory of relativity or atomic theory.
Theory does not imply doubt. It is a coherent group of propositions meant to explain facts about the world. Evolution, the theory, explains how evolution works. Evolution is also an observed fact. We have seen it working inside human bodies, in the lab and in the field. We have also seen the dawn of new species, not just changes to an existing one.
Creationists routinely lie that this is not so. They claim to be true anything they wish to be true. Facts never get in the way.~ Roedy (1948-02-04 age:69) Why Evolution is True
