Another point. Everyone claims that their religion is true and the rest are myths, but all religions operate the same. Christianity is just as geographically dependent as witchcraft is. You're trying to tell me that Christianity is real and there's an actual God behind it all, but it spreads through normal cultural contact just like myths do, it's passed on through cultural indoctrination just like myths are, and it can't provide any more evidence than all the other religions in the world can. Just like Zeus, a myth, the Christian God couldn't cross the Atlantic ocean until boats were constructed and human beings crossed the Atlantic. Your God acts exactly like a myth.
The anthropological evidence shows us that even when there's nothing supernatural of any kind going on, people will still devote their lives to absurd supernatural beliefs (scientology, David Koresh, Heaven's Gate cultists, etc). You of course are positive your religion is different, as every believer is, including the scientologists. They are claiming that their religion is true and that yours is just a cultural artifact.
But not a single one of you can provide more evidence than any of the rest. It should bother you that you are in the exact same category as scientology and alien abductees.
You use this exact same argument to disbelieve in all of the other claims of supernatural beliefs out there. And everyone who isn't a Christian uses it against Christianity. And no one thinks it applies to their religion, the one the vast majority of the time was gained through cultural indoctrination.
