That in and of itself doesn't constitute proof. That's the same type of thinking that a person uses to prove to themselves that the horoscope crap in the newspaper is legitimate. It's called seeing what you want to see. Or in the medical world the placebo effect, the power of suggestion etc. I don't try to convince God people that they should become atheist. Some of their claims and thought processes though are just as weird as the overly enthusiatic supporters of so-called "natural/alternative" medicine. Just because a lot of people believe something doesn't make it a fact.
