There is no salvation outside the Magisterium(as defined by the Infallible Constitution of The first  and only Vatican Council) of the Roman Catholic Religion.  Some  on this Earth are familiar w/ this concept---it does not necessarily mean that Jesus has not been on another planet, it just means that the nature of Revealed Truth has given us no evidence of such.

It needs to be remarked that just as VI Catholics teach that everyone else frys, Judaics and Moslems teach the same thing--there is no Salvation outside.......
