The question at hand: If alien life were discovered, would Christians have to share the Gospel with them? It's not a new question, although it's usually expanded to consider the role of cosmology in Christian theology as well. CS Lewis wrote a series of books about it, for example.
There's a few ways of looking at this.
- The positive case would state that, since Adam's sin caused the Fall to ripple out through all of creation, then aliens would also be in need of redemption.
- The negative case would state that, since any alien life would not be descended from Adam, they would not be inheritors of Adam's sinful nature and thus not bound by the details of Christian theology.
- The demure case would state that, since the Bible says nothing, positive or negative, about life beyond Earth, then speculation about the theological ideas surrounding it is improper.
Dr. Mohler argues the latter case, incidentally.
As for me, I'm a contrarian on this topic. The question is hypothetical, but I'm convinced that the possibility of alien life is so poor that it's not worth taking seriously. Allow me to explain.
