No it doesn't. There are different quantities of evidence for every claim. For instance, if you told be you had a pet bird, I could believe you just at face value, because the claim is not that significant. I could still be wrong, but changing my belief on that claim has no impact on my life. However, if you told me you had a fire breathing dragon as a pet, I would require much more evidence than just your say so. And now my belief on that subject is disbelief until substantial evidence is brought forth.
Technically, and skeptically, what you should be believing in the above example is that
I have said I have a pet bird. And yes, you'll compare it to your version of how the world works (i.e. asking yourself, "Is this true?") in order to form a belief of your own regarding whether I reasonably and actually do have a bird, or a dragon. Until you meet my bird, though, or see some evidence of it, investing in the idea that I, in truth, do have a pet bird is taking what I say entirely on faith.
All beliefs, I think, should be held in the same regard, since, for each of us, they uphold the truth of the world.
Almost everyone has beliefs. I believe that the scientific evidence for evolution is overwhelming, therefore, I believe evolution is the best explanation for the diversity of life. I have that belief based on scientific evidence. And I don't think it's unfair to require the same type of evidentiary standards for every claim, especially outlandish claims.
It's not unreasonable to require such a standard for facts, that thing in which we are investing belief. But belief itself is an extremely simple idea: Is it true?
