Conclusive proof of God

[Aoi Magi]

If you think the plausibility of God matches that of vampires and faeries which are are always presented as fantasy then you have obviously closed your mind to the concept of God.

Plausibility of god = plausibility of vampire, because:
1) Both are supernatural
2) Both are scary (as per most major religions)
3) Both demand blood/sacrifice (as per most major religions)
4) Both has many people believing in them (many believe vampires are demons).
5) Both has the same amount of proof. zip, nada, none whatsoever.

So if you don't entertain the idea of vampires on the same level as the idea of god ("disbelief" or "unsure" or "spiritually proven" or whatever), then you are being closed minded.

Now as a "thought experiment", how would a vampire prove itself to mankind? and should it bother proving itself to mankind?
