Faith = Evidence

You don't need to have faith in something if you can see it. Faith is needed when we can't see. However, that has nothing to do with evidence. As such, faith is believing in what you can't see because of evidence.

Faith

Current popular science (SciPop) propaganda is that "faith is belief without evidence." However we all have the same evidence (Matty's razor) so the meme fails as a definition of faith.
