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.
I can only say one thing on this, the universe is massive, if God put us here then he could have put other life elsewhere. Maybe there are all sorts of worlds at different stages. I like to think God has a sense of humor at times.
