The problem with "more evidence" is that much of it has been hearsay. Person A tells person B something. Person B repeats person A's claim to person C. Person A then talks to person C, and person C says it must be true because they've heard it from multiple sources.

Hearing something a lot doesn't give it additional credibility.
