I was thinking the other night that if some alien archeologists were to look at our little planet thousands of years from now, they might come to the conclusion that the Irish and the Chinese were the world's two greatest cultures -- because there are Chinese restaurants and Irish pubs everywhere. Perhaps the aliens would think that these were our temples and would interpret our going there in droves as signs of elaborate worship ceremonies.
Then I thought about the temple of Mithras in London, or the temple of Aquae Sulis in Bath, and on and on. What if all these ancient Roman temples were, in fact, Roman theme pubs? What if no worship took place at all, and all these temples were simply places where people gathered to pretend that they were Roman and tell each other, "Well, of course, my grandfather was born in Rome," and "The mead they serve here isn't as good as the mead served in Rome."
