Sometime after Galileo died, the church realized that attacking a poor astronomer (who had strong Christian convictions) was probably their worst idea since they asked Thomas Aquinas to write a little book about what he believed. Today, near the train station in Rome, you can see this large church that tells the legacy of Galileo and even shows a film of the moon landing. In this video, one of the astronauts mentions Galileo's predictions about gravity on the moon and carries out the experiment that Galileo had always dreamed of. Check it out:
Today, something new and different is going on in Rome. Since life on other planets is a possibility, the Vatican does not want to be caught off guard. It's important to consider the theological ramifications of extra-terrestrials and to consider what the church's role should be if an encounter with alien life took place.
...in the interview last year, Funes told Vatican newspaper L'Osservatore Romano that believing the universe may host aliens, even intelligent ones, does not contradict a faith in God.
"How can we rule out that life may have developed elsewhere?" Funes said in that interview.
"Just as there is a multitude of creatures on Earth, there could be other beings, even intelligent ones, created by God. This does not contradict our faith, because we cannot put limits on God's creative freedom."
Funes maintained that if intelligent beings were discovered, they would also be considered "part of creation." (Link)
I agree - nothing about aliens challenges my faith.
However, the writers over at AnswersInGenesis.com do not agree - they maintain that only the Earth can hold intelligent life and that no aliens can exist, and they insist that this can be determined by reading the book of Genesis. That's a remarkable claim - not a single Biblical scholar in history seems to have come to this conclusion, so the folks at Answers in Genesis must be pretty confident in their ability to interpret scripture. (I linked to that article and wrote my opinions about it here.)
At my old job, some co-workers said that if aliens were discovered it would nullify the Christian faith - I wanted to bang my head against the wall. When did Christians get this "anti-E.T." reputation? Let's choose our battles more wisely. Also, I'm going to join the Vatican in watching the skies.
