"This idea takes more "faith" than a whole room full of evangelical Christians and a whole convention of evolutionary biologists combined."
Not really. The same amount at most. There's no proof for either belief.
Hey, this brings up a question I never thought about before though: Where do Christians stand on whether or not we are the only inhabited planet in the universe?
"Where do Christians stand on whether or not we are the only inhabited planet in the universe?"
We should prepare for war against the planet Mars. Why do you think it's named after the "god" of war. /sarcasm
Personally, I think the universe is mankind's playground. The stars are just pin pricks of light for use to use as celestial navigation. I view any spiritual and intelligent creature outside the human race with great suspicion until it's determined that it's "of God". E.T. is the devil. T.I. from the abyss is the devil. The Virgin and the Eucharist is our pillars to moor our ship.
There's solid proof against alien visitors (the ol' speed of light limitation bugaboo).
For those Christians who interpret Genesis literally, life on other planets may or may not present a problem, depending on how strictly the early Genesis passages are read.
For those Christians who view Genesis as a representation that God is the Creator and that humans are His greatest creation, life on other planets is a scientific curiosity but does not conflict with their beliefs whatsoever.
The Catholic Church does teach, however, the existence of bodiless spiritual entities, both good ones and bad ones. Though they are not physical, they have the power to "organize" a physical appearance. I have no doubt that false scriptures (Koran, Book of Mormon, what have you) and false apparitions (some of the strange "Marian" apparitions --- not endorsed by the Church ---which produced false prophecies and disobedience) may well have involved rebellious spiritual entities who successfully deceived the credulous.
