No offense to the UFO guys, but the Bible is a bit more substantial. I understand your objections, and I can appreciate them, but the Bible wasn't written by one person, or in one time. The Bible was written over centuries, by people in various walks of life. It references works of authority to the people of that day. It was never the intention of the authors to put it over on unsuspecting people, if it was they did a pretty poor job. From my reading, the authors were being sincere. Yes, they may have been sincerely crazy, but then they all were, kings, farmers, fishermen, rabbis, regents. They didn't believe they were writing fiction (fiction is a rather new invention, by they way.) They might have all been lying, but they might have crafted a better lie, been a little more "consistent", etc. Your argument just doesn't ring true.
I'm not trying to make a Christian out of you, but if you want to be critical of the Bible, you should try harder than comparing it to the Easter Bunny or the Power Rangers.
