I just posted another installment on eschatology (end times) over on my Naked Bible blog. Again, the goal in that series is to get people to understand that the typical “there’s going to be a Great Tribulation, a rapture, and a millennial kingdom in Israel” view of end times is *not* self evident in the Bible.  But it is precisely that view that is presumed in the Christian “fundamentalist” community that seeks to parse UFOs and aliens as part of the end times.  You need to understand (1) where that theology comes from / how it is argued, and (2) what its weaknesses are before you can understand my concerns with linking biblical eschatology to the UFO / ET issue.
