They were real a long time ago. We just don't know WTF they are. Or that's what they're telling us anyway. I saw one with a group of others in 1980, and my father and his co-worker saw a huge cigar shaped one back in the late 60's on a pipe line survey out in the wilderness. Both sat there for a while and then went straight up and vanished. Maybe it's a hickup in the matrix.
