All the languages on Earth were designed by extraterrestrials in order to facilitate the progress of events on Earth while making it more difficult for the Earthlings to realize what is going on since they all do is not speak the same language. You can see clues to this if you use unconventional logic. For example LATIN. Replace the T with an E (as in ET) LAEIN and respell it as an anagram and you get ALIEN.
A recent article published tries to claim that UFO sightings are just Top Secret Military Aircraft the public may not be aware of.
Every day Earthlings are bombarded with the same repeating patterns of information. Yet, just like clockwork, the Earthlings just absorb it and make no progress for themselves while helping the Humanoid Extra Terrestrials Living Among Us (HETLAU) to accomplish their goals.
SETI (IS ET) was founded in 1984.
At best, most Earthlings are only willing to go as far as "ET" and "UFO's" might exist. Any further, such as they have made contact with our government, simply pushes the envelope too far. The further you press the issue, the more you are considered to be delusional or even schizophrenic.
