In response to Neb Maat Re, a less hopeful, but equally probable scenario is that a Yu-Gi-Oh fan doesn't become interested in Egypt at all, but instead goes on believing that Yu-Gi was an ancient Egyptian Prince who used magical cards to fight evil priests by releasing 'Winged Dragons of Ra' and 'Obelisk Demons of Seth' to defeat them. Really though I don't care. So long as there are children, like Neb Maat Re's son, who know what they're talking about, I think that we need not worry that knowledge of Egyptian culture be lost forever. My only thought is that it is disrespectful that the Japanese have contorted the Egyptian deities.
Continuing on from Si-Amun's point, on T.V yesterday I saw a re-run of a program about the Temple of Edfu. A fat, smug American (no generalisation is intended here, honestly!) was looking at the beautiful statue of Horus at the entrance to the complex and shouting, "They worship a bird! Pahh! How dumb is that?! A bird- a bird can't even talk. . .etc."
To me, the idea of worshipping something that commonly appears in nature, and can be seen to possess powers beyond that of humans (like flying for example) makes far more sense than worshiping something that cannot be seen, or even described. I am an agnostic also I should say, and am in complete accord with Si-Amun.
