A great question. I think my lack of extraterrestrial.. or whatever expriences have played a part in confirming my lack of belief. I must admit that I'm a sucker for other people's stories though. Kev's was nice - but I think that his seagull may have had previous human handling and it was just one of those coicidences in life. (always a rational explanation to this stuff).
I watched an extremely moving program about aids last nite and one woman told of her spiritual experience just before her child died of aids. I can't account for some of these very extraordinary moments, but I am sure that our brain is capable of giving us illusions when we are deeply challenged.
