1. Do I believe other life has existed, does exist, and/or will exist elsewhere in the universe? Yes, with pretty close to 100% confidence. 2. Do I believe other intelligent life forms visit earth in their flying saucers, abduct people, anal probe them, abduct and slaughter cows, build pyramids, and - apparently - crash often? No, not really. I mean, I can't rule it out, but my personal subjective Bayesian prior towards this notion would probably be something like 0.001 or so. But that's actually up from years past, as we learn more about more possibly inhabitable planets that are closer to Earth than was previously known, etc. Basically both of my positions boil down to the same factor: the size of the universe. It seems to me that the universe is too damn big to not have other intelligent life. But also, it's so big that the other intelligent life is likely to be too far away for us to have any interactions with them.
