I'm going to take the Alexander UFO Religious Crisis Survey:
1. “Official confirmation of the discovery of an advanced, technologically superior extraterrestrial civilization would have severe negative effects on the country’s moral, social and religious foundations.”
We need to distinguish between what would happen and what should happen. If that happened, I don't think that discovery ought to have any negative effect on the foundations of Christianity.
But in reality, it would become a new religion for many clueless people, including nominal Christians. They'd seek moral and spiritual guidance from the wrong source.
2. “My congregation would perceive any contact made with a technologically advanced extraterrestrial civilization, direct or indirect, as a threat.”
Of course, that's hypothetical. It would only be threatening of the aliens were threatening. A hostile invasion. That scenario.
But in principle, contact with an alien civilization would not be intrinsically threatening. Mind you, it would certainly be disruptive.
3. “The discovery of another intelligent civilization would cause my congregation to question their fundamental concepts regarding the origin of life.”
That's a non sequitur. If they exist, they're creatures–just like us. God made them.
4. “If highly advanced intelligent life exists elsewhere in the universe, the basic tenets of religion would be present.”
If they're unfallen aliens, then they'd worship the same God as Christians do. Mind you, that depends in part on how much divine revelation they are privy to. It's possible that God reveals himself more extensively to fallen, but redeemed creatures like us.
5. “Genetic similarities between mankind and an advanced extraterrestrial civilization would challenge the basic religious concepts of man’s relative position in the universe.”
That's no different than the issue of genetic similarities between mankind and other terrestrial lifeforms. So that wouldn't add anything new to the issue.
6. “If an advanced extraterrestrial civilization had religious beliefs fundamentally different from ours, it would endanger organized religion in this country.”
No, that would simply mean they're a fallen race–or evil spirits in alien guise.
7. “Scientific confirmation of contact with an advanced extraterrestrial civilization is probable in our lifetime.”
I doubt it.
8. “It is unlikely that direct contact with an advanced extraterrestrial civilization has occurred or is currently ongoing.”
9. “My congregation would question their beliefs if an advanced extraterrestrial civilization had no system of religion.”
Same answer as #6. Again, though, assuming that they even exist, there's no presumption that God revealed himself in the same detail to every alien race.
10. “If an advanced extraterrestrial civilization proclaimed responsibility for producing human life, it would cause a religious crisis.”
Same answer as #6.
