I'll just interject to add another voice to the side of reason here.
Faith by definition is not the way to distinguish what is true from what is false.
We determine the difference using logic, a form of which being science. Accumulation of evidence to support a theory, so that it becomes quite obviously fact - like evolution, for example.

'Faith' is just a word to denote belief in a thing for which there is absolutely no evidence - God, Russell's Teapot, Flying Spaghetti Monster. But can also equally well be applied to beliefs where the evidence is stacked against it - flat earth, creationism etc.
