Osiris......vs Jesus

If you are Christian you may want to stop reading now.....there is a theory that the story of Jesus Christ is actually a more modern retelling of the myth of Osiris and how he was killed and resurrected there are a lot of similar pieces of information in both stories right down to similar ideals of the resurrection process and how both were basically Shepard’s of the dead and would grant them happiness resurrection and everlasting life....in the myth of Osiris Isis finds his slain body and briefly returns him to the land of the living....Jesus briefly returned in the bible to appear before various people before returning to the afterlife as did Osiris.....please do not get offended I am spiritual not religious but if you are overly religious I do not mean offence just sparking a discussion.
