Very good article. I have wondered about this subject over the years, especially regarding the fact that so many thousands of witnesses have told similar stories about abductions. And any advocate for the abductees becomes a major target of defamation. Harvard psychiatrist John Mack comes to mind.
There are many high ranking and top secret-clearance individuals who swear that there are aliens here and that among the tens of thousands of UFOs, some are actually not human-made or operated. There is a refusal, out of fear and ego, to accept that reality is not what we have been led to believe it is by the forces of religion, science, history, and other institutions of we limited human beings.
What can we do with any of this information? For one we may entertain that the life we live and commonly call reality, is not all there is to it.
