On Fairies, Pots of Gold and Astrology

Atheists and Jesus - Beliefnet:

"If you could explain what I should reject for all of the above I might be able to answer your question. Must fairies be visible to everyone in the world for them to exist? Must they be visible to anyone in the world? If fairies affect the actions of those who find fairies helpful even if they are never visible, is this data acceptable as to the existence of fairies as conceptual entities?

I have actually seen the end of a rainbow. Technically a halo interrupted by my body which appeared through an artifact of sun position and body position to end at my pockets. The pot of gold turned out to be a few credit cards in one pocket and a bit of change in the other. Must the pot of gold be literally that, or were a couple of credit cards with substantial unused credit lines a modern material equivalent? Or does the fact that the credit lines are imaginary entities in the bank's computer make them unreal? If I use the credit line to buy a pot of gold, does that reify the credit line or the pot of gold at the end of that particular rainbow?

Must astrological bodies actually have a measurable effect on people at the time of their birth to consider astrology to be true. Or since astrological signs correlate with seasonal variations and birth times correlate with conception times, might there be some scientific correlation with personality types and birth and/or conception times? As a speculative example, perhaps a child born in the depths of winter to parents affected by Seasonal Affective Disorder might have less loving care in the critical first few months of life. This could have permanent effects on personality characteristics. If astrologers are using the constellations as a marketing tool for personality analysis guided in part by birth date, does this invalidate astrology?

Just for the record, I consider fairies to be conceptual entities occasionally useful for entertainment value only. I know of no other values associated with fairies. As for the pot of gold, as an allegory for hope at the end of a storm I would find it of some value even though non-existent physically. In spite of my confirmation of its actual existence in one special case. Astrology I consider to be useless, as the potential for scamming totally outweighs any folklore basis for the readings."
