U.S. Has No Explanation for Unidentified Objects and Stops Short of Ruling Out Aliens

[elevator]

11. As I've said many time...there are two possibilities Human or Alien Tech.

Either it's ours, another country's, or some hidden group. We completely deny it is ours. Doesn't men it's not. If it is technology developed by another country, how have they kept it a secret, or why have they not used it to gain power? If it is an unknown group that developed it...same thing how has it been kept a secret? The latest report would have us believe that these sightings of engineered craft in the sky goes back a couple decades, when in reality they go back many, many decades pre-dating our first manned flight. It is beyond belief that this technology was developed and kept secret by anyone for that long. The videos released by the Navy in the last few years are interesting, but debunkers are having a field day, but not successfully imo. By the way several military officials have stated that they are in possession of literally dozens and dozens of videos taken by pilots on normal cameras that clearly show these craft/objects. Anyway please answer the question. If it's of human origin, by whom and how has it been kept a secret. The only other human genesis possibility is from humans from the future.

If you cannot accept, or make a believable case for human origin, then the only remaining option is alien.
