If I was to break down what it was, kind of decision tree style, I'd guess it's - Hoax 50% - Non-Hoax 50% - Optical Illusion 80% - Unidentified/Secret Military Tech 19% - Other 1% (a generous 1%, probably fairer to be 0.000000001%) - ET 33% - Future human 33% - Interdimensional 33% - Other (though manifestation, spiritual/religious, trickster) 1%
