Everyone has their own beliefs about extraterrestrial life. Theories and beliefs on this subject are more contentious than Various factions of Christians fighting over pre-trib vs post-tribulation rapture doctrines.
I am surveying not beliefs but actual experiences amongst our ranks. If you have had one or more eyewitness firsthand accounts of UFO's or ET's, please list your experiences here.
About 20 years ago in the early morning hours (still dark) as I drove to work, there was a huge rectangular object sitting on a hill about half a mile from me, a hill that was and still is not built on, just trees and a field. The object was dark but still observable against the dark sky, and there were four square windows along the side facing me with a soft yellow light emitting from them. The object was at a slight angle, maybe 3 degrees, off of horizontal as I was viewing it.
I pulled off the side of the road to watch for about a minute. I did not see any biologics -- human or otherwise -- during this event, but it just sat there, easily as large as 50 yards wide. I was just stunned by what I saw, but I realized that I would be late for work, so I put my car in gear and drove on.
To this day, I still don't know what that was, and each time I pass that spot to this day, there is STILL nothing built on that hill, still just trees and a field.
