If something is shown to be true by a preponderance of facts, then it is not "faith" to believe that it is indeed true.
Evolution has a massive accumulation of evidence to support it, and any one of several methods to falsify it have not been found.
This last point is especially interesting. Since the Discovery Institute has assets and people and has existed for 25 years or more, they have yet to be able to falsify Evolution. And the attacks on Evolution go back before the DI. If Evolution were false, then physical evidence should be able to be found that would falsify it. They have not found it.
With so many people, trying for so many years, and they have not yet found genuine evidence that will falsify it, that makes Evolution just about the most solid scientific THEORY we have.
Evolution is seen as only faith, in those religious faithful who see Evolution as a rival to their legitimacy. Ironicly, science does not see faith as being a rival to Evolution. There are many believers who accept Evolution, including the official doctrine of the Catholic church and several other large denominations.
Despite the persecution complex of some religious people, Evolution is not trying to attack religion. It is religious people who are attacking Evolution. Science is merely defending itself. My fear is that in this defense process, that the faith of some religious people may be harmed.
Then why is the scientific community not willing to say case closed and assert it as undeniable fact?
