But how far beyond? Jay Manifold discusses the potential limit of civilization, and links to another article on the same topic titled "The Physics of Extra-Terrestrial Civilization". Lots of somewhat-reasonable speculation, that's fun to think about.
Personally, I'll be quite surprised if we ever find extra-terrestrial intelligence, and I'll be only a little less surprised if we find ET life of any sort (after all, if there's any life, then there's probably intelligent life somewhere). Rather than waste time searching for such things, I think we should concentrate on getting as many people off the planet ASAP.









So much of Christianity is founded on that - that Earth is the home of all sentient beings. I think that'd shake us all up quite a bit if there were life on other planets.

Ever read C.S. Lewis's Space Trilogy? This has helped me come up with a half-baked idea about other worlds that are unfallen. Just in case we come across some smart green men in our space travels.
HLN,
I thought Christianity was based on teachings in the bible, which is mute regarding ET life. At least what I've read it is. Do you have scripture to back that up? I'm not saying I disagree, I just want a little proof is all.
