The discovery of intelligent aliens would be mind-blowing in many respects, but it could present a special dilemma for the world's religions, theologians pondering interstellar travel concepts said Saturday (Oct. 1).

Christians, in particular, might take the news hardest, because the Christian belief system does not easily allow for other intelligent beings in the universe, Christian thinkers said at the 100 Year Starship Symposium, a meeting sponsored by the Defense Advanced Research Projects Agency (DARPA) to discuss issues surrounding traveling to other stars.

In other words, "Did Jesus die for Klingons too?" as philosophy professor Christian Weidemannof Germany's Ruhr-University Bochum titled his talk at a panel on the philosophical and religious considerations of visiting other worlds.

"According to Christianity, an historic event some 2,000 years ago was supposed to save the whole of creation," Weidemann said. "You can grasp the conflict."

Here's how the debate goes: If the whole of creation includes 125 billion galaxies with hundreds of billions of stars in each, as astronomers think, then what if some of these stars have planets with advanced civilizations, too? Why would Jesus Christ have come to Earth, of all the inhabited planets in the universe, to save Earthlings and abandon the rest of God's creatures?

This is the only picture available of a UFO that has been terrorizing residents in the state of Missouri for the past few days. Apparently the brightly-lit vehicle has been flying low over cars on the highway, and appears to break up into smaller craft. Dozens of witnesses have reported seeing it, boosting Missouri to a "UFO Alert" level 3. The state had the 8th highest number of UFO reports in the U.S. last month. What's going on?

A woman who saw the UFO earlier this week in a car with her family near Kansas City reported to MUFON:

We saw this object that had shape of stealth bomber that had green and white lights hovering over the highway. At first I told my husband and children that I thought it was a blimp, but as we got closer it was doing weird maneuvers."

We turned around to get closer, and by the time we got close enough it shot if like a rocket. There was another object in sky that it flew over and the light on it was a white, very bright light. I then called my father - retired navy - to ask him if stealth bombers hover and have green and white lights - and he said 'no.' He said that it might be a Harrin. So I looked it up and it didn't look like it either. So what was it that I saw?
