I am a personal believer of unified theory, and I am curious if anyone else has thought about what I am about to say. Is it not possible that, all religions are connected? That in religions such as christianity and islam, paganism, and judaism, etc, that people are taking them waaaaayyyy too literally? Think about it, it makes since that alot of those illogical things could be metaphors. God is the sun, because the sun gives off energy which produces life. When the big bang theory happened, the planets formed from the sun, therefore the sun could be said to be their creator. That the sun and planets all actually live, but in more of a spiritual kind of life?
The "great satan" is the genetic inner animal, as opposed to being an actual person or living entity. Perhaps buddhism was more straight foward in that it was less metaphorical, but it still speaks in riddles. Essentially, you've got the same message in all of them. The only major difference is in how they were delivered.
You'll also notice that many of the same names and symbols keep reappearing from one religion to the next. Names like Jesus, michael, moses, Abraham, and even some old pagan dieties.
