I don't think any rational member here thinks we are the center of the universe, so to speak.
I for one, believe intelligent live exists elsewhere in the vastness of the Universe.
That does not mean they have paid us a visit. There is zero hard evidence otherwise. Zero.
Having spent nearly 4 decades in service to the US, with significant time in "the building" as part of many highly sensitive programs, I would have been exposed to such info. It simply isn't there. Nope, no matter how bad some want it.
Zero. Zilch. Nada.
Eyewitness testimony can simply be wrong and definitely inaccurate. Seeing may be believing...but not necessarily reality.
Someday, we may have solid evidence. To date, it hasn't happened.
Don't let political "interest" make you think something is true (in the actual sense). Catering to constituents is not for anything other than votes.
