As we were discussing the issue of science and faith today I thought that it might be interesting to look at this issue from the other side of the coin, what I mean is in a future in which we have aliens and what not, as depicted in various films, does a Christian's beliefs become questionable? Since Jesus died on the cross all we have had to worry about is humans. Jesus came to earth as a man, he died for the sins of man, etc. Perhaps the reason that "God is dead" in so many science fiction stories is because in a world with sentient beings of all different shapes and colors it might become difficult to explain to them that Christ died for all our sins. What if he didn't die for the Martians or the Kryptonians? How would a future theologian explain this to an alien being who doesn't even share the same blood color as we do? How do we hold to our beliefs when faced with this question?
