How is asking for evidence close-minded? Having 3000+ years of personal accounts is meaningless when compared to hard, physical evidence. Again, personal anecdotes is not evidence.

Personal attitude shouldn't be relevant when you're talking about evidence. One of the main attributes of evidence is precisely that it is objective and not personal.
