Christians think they have a unique event...Christ Rising from the dead. But, of course, that myth has been around for ages. Long before the sandal wearing hippie ever walked the dunes between Jerusalem and Galilee, rode an ass in Damascus or faced his fate on a cross planted atop a hill, mythical characters were rising from the dead.
So, really, what we have here is myth sharing. Clearly, since Jesus came after all these other resurrected characters from what amount to fairy tales, reason dictates the Jesus myth too is a fairy tale.
Now, of course, Christians will say those other resurrections are myths but the resurrection of Jesus was real. Of course, we know better. Fact remains, Jesus myth is just as contrived as the Osirus and Achilles myths. Is there any doubt?
