Edit: Fairies, elves, unicorns, minotaurs, etc., etc., are all said to be non-existent for the sole reason that there is no evidence for their existence.
First, one always has logical arguments that something
cannot exist.
Second, with fairies, elves etc. there is no reason why they
must exist.
(We can get into a debate over whether the philosophical arguments for God's existence work or not -- but it is important to note that no one has ever proposed, or even tried to propose, philosophical arguments for the existence of fairies, elves etc.)
Metaphysically speaking, there is a fundamental difference between beings like unicorns, elves, fairies (and even human beings!) and God.
Empirically speaking, the persistence of religions, religious phenomena and personal experiences of God/the One/the Other requires a reasonable response. Even if the response be one of disbelief, it is one that calls for a different degree of seriousness to claims about fairies, elves etc.
Finally, the "absence of evidence" cited by the original poster is an entirely ego-centric one. His argument is no more viable than a person claiming that the stars are really little halogen lights on an enormous black ceiling because no one has given him
convincing arguments otherwise. That "convincing" bit (which the poster also cited) indicates the level of subjective opinion he brings to the table in this discussion.
RWillis probably won't agree with the first couple of points I stated; but I think he and I agree on the last one -- an individual's obstinacy is not "evidence of absence".
