Quote - will they go to hell?  

You know, since they never been to earth, they probably haven't heard of the guy.  Just an interesting question that popped into my head.

Once we learn to communicate with them, we may learn that they have something similar to Terran (religious) myths, legends, and other stories, but it's just as likely that they'll have something completely different even if they have the concepts of "God", "Sin" etc.
