Why UAP's, UFO's (presuming they are Alien controlled) are a threat but don't have to be

[beecee]

Last year a report was released on UFO's/UAP's https://interestingengineering.com/government-ufo-report-military-taking-it-seriously  It was of course nothing more then the same old, same old, in that some sightings are unexplained/unidentified at this time. Nothing new here.

But there was I believe one factual assumption, that was while these so called "incursions" into a nation's air space, in the manner that they are/have been happening, ( you know, mysteriously flittering in and flittering out again, kidnapping individuals and conducting medical experiments etc) they can be seen as a threat to national security, due to their unknown nature.

If they are Alien controlled, and that obviously would be by an advanced species, why are they continuing with such behaviour? Why not make their presence known? As per my reasonings in the other Alien thread, I don't really see them for seriously wanting of anything, and if they did, why not land, make their visitation known to us, and ask or negotiate. We could even continue as partners in a shared space-faring exploratory vane. As per for example,  https://www.youtube.com/watch?v=_yIp2huYgD8  Obviously that isn't happening because so far all we have been witnessed to, is unidentified and unknown phenomena.

There is also reports that more "classified information"will be released next year...https://interestingengineering.com/scientists-will-release-3-terabytes-of-new-ufo-data-in-2022 My prediction, nothing new and again, the same old, same old.

The sensationalists claims that some or all of these are Alien incursions is dealt with far more scientifically with SETI....https://en.calameo.com/read/0048123637a4a64903b14

"So, while the UAP investigation relies on the interpretation of chance observations, SETI relies on deliberate experiments. There is a vast divide in the assumptions made for the two activities, and they are fundamentally dissimilar.

Will the first compelling evidence of extraterrestrial intelligence be found in the atmosphere of our planet, or in the hundreds of thousands of star systems that pepper the nearest reaches of our galaxy?

We still don’t know.  But if the pending government report indicates that there is a possibility that at least some UAPs might, indeed, be of extraterrestrial origin, then perhaps there will be an effort to pursue their study using the precepts of well-designed science experiments".

Like SETI, I believe we are probably not alone in this universe and that advanced intelligence exists somewhere, sometime. 

Like those at SETI and most scientists, I accept that as yet, we have no real concrete evidence of ETL anywhere, anytime.

Like those at SETI and most scientists, I suspect that the first real evidence of ETL, will be some simplified organism or such, and not any advanced species.

Like those at SETI, the great barriers between interstellar and/or intergalactic contact are time and distance.

Just my 5 cents worth on this topic.
