Several news websites, including the Huffington Post, have posted articles representing--and misrepresenting--recent comments by Australian-born evangelist Ken Ham regarding our space program and the possibility of alien life.
First the misrepresentations.
They reported Ham saying that we should end much of our space exploration program because we will never find alien life. In Ham's view, God created the earth as a special place for human life and as a stage for the drama of God's redemption of man. That implies that evolution cannot be true and that no life forms have emerged on any planets other than earth. In fact, according to Ham, the primary reason scientists explore space looking for extraterrestrial life is to prove the truth of evolution. Neither NASA nor any one working in an space observatory will find alien life forms, so it is a waste of time.
In fairness to Ham, he never said to stop exploration of the heavens. In fact, he encourages it. He says he remains confident that the expanding knowledge of worlds beyond our own will prove his point that no intelligent life exists beyond earth.
Now the representations.
These same web sites quote him asserting that another reason that extraterrestrial life does not exist is because of the meaning of the gospel. Adam's fall from grace impacted the entire universe. That would include any extraterrestrial life. But Jesus offers salvation only to those who hear the gospel, repent, and believe. That would exclude aliens, implying their damnation to hell by God:
"And I do believe there can’t be other intelligent beings in outer space because of the meaning of the gospel. You see, the Bible makes it clear that Adam’s sin affected the whole universe. This means that any aliens would also be affected by Adam’s sin, but because they are not Adam’s descendants, they can’t have salvation. One day, the whole universe will be judged by fire, and there will be a new heavens and earth. God’s Son stepped into history to be Jesus Christ, the “Godman,” to be our relative, and to be the perfect sacrifice for sin—the Savior of mankind."
Now Ham subsequently denied the report that aliens go to hell. He says that because he does not believe in extraterrestrial life, then he obviously never made such a claim.
It appears in the above passage, however, that he made a counter factual argument (counter factual at least in his own mind) which suggests that conclusion.
Ham spares readers the details--they know them already. Adam's sin made all men sinners, either through generation or imputation. Generation means inheritance of sin through genetics. Imputation means that Adam in some sense represented all humans who every lived and God imputed the guilt of his fall to all humans. In contrast, Jesus, the second Adam, obeyed God. His righteousness will be imputed to not all humans, but those who believe in him.
Christian dogma also holds that Adam's sin not only brought God's curse upon himself and his progeny, but also upon all creation. The earth became a more inhospitable place and animals began eating each other. Readers may wonder why God would curse animals, who have no free will and cannot sin against God. According to Christian dogma (or at least some of it) God cursed the animals and the natural world because God originally created them for man's use.
Of course, because the Bible contains absolutely no notion of extraterrestrial life, its possibility reveals the incoherence of Christian dogma. If extraterrestrial beings exist, God must have created them. How can God hold them accountable for Adam's sin? And how can they avail themselves of salvation when they have never heard of Jesus.
The only answer is to deny extraterrestrial life exists.
