[Cthulhu could be real. Don't discriminate, John.]

I fail to see how one set of gods existing precludes all others from that same right. Greek mythology is only the tip of the iceberg in all of humanity's mythological history. Are you denying the possibility that the Norse myths, Egyptian myths, Chinese myths, Japanese myths and all other myths are real? The myths have to come from somewhere, and since it has been proven to us that the Greek gods and goddesses exist, why should we doubt the others do?
