Sometimes I visit an unfamiliar European city and I follow the tourist trail, seeing the sights. Usually this involves visiting the main cathedral which is usually of astounding proportion and workmanship. I find myself thinking, these people who built this must be right, their deity must exist or it would not make sense to build something like this.
Then I find myself somewhere else, marvelling at the skill, time and effort to build a massive temple to a completely different deity.
Then I find myself yet somewhere else where an enormous place of worship has been build to yet another deity.
They all tell me to worship a particular deity and often want exclusivity in this worship.
I worship none of these deities but I can still stop and look and admire the grandiose works of deluded fools.
