This is a subject that fascinates me. I believe we are not the only planet with life and that somewhere out there is a civilisation far more advanced than our own. Have they visited us? Maybe.

While I think the majority of cases are either misidentified, a good portion are secret military and government programs.

What's left are a small percentage of cases so baffling that no explanation other than alien can be put forward.

Thanks for this excellent write up.
