But they’ve always been reported high and low, near and far, day and night.
As for their being aliens, again I ask: how do you know? What can you base that on?
There are numerous "disclosures" that have occured in the past. Dr. Edgar Mitchell is but one of many. There have been four death bed accounts of the Roswell crash by key players in that incident.
After reading UFO lore for over twenty years, a pattern emerges that tends to "separate the wheat from the chaff".
Numerous foreign governments have already released files, and their explanations include ETs in some cases.
If you will examine all of that material extensively, you would see that most of the evidence tends to support ET contact. I have not arrived at this conclusion without a lot of reading and contemplation.
