Also, having thought about it over the years, I think that the amazing, perfect seeming large, triangle UFO with "light bulbs” at it's tips was from God. I think the UFOs off in the distant, which friends and I saw fairly often, blinking, standing still, doing turns, etc., kind of putting on a show, were the enemies crafts. Not sure about the huge one in a cloud. The last smaller orange crafts, somehow, I think are more individual crafts of The LORD’s.
When the Bible tells us we many entertain angels unaware, I think that they come and go in smaller crafts to and from local areas. I think they end up mingling in among us, doing things to minister to us unaware, and maybe at times testing how godly our reactions to those we don't know are.
During the 70's my friends, my sister and I were not Christians. It may be that spiritual crafts had us in there attention because at that time there was a battle over our souls and pending salvation. For some reason, unknown to me, The LORD let us in on it, at least to a certain extent.
