Indeed it is.

Until its not.

I remember seeing some old sci-fi movie (1920's--silent movie, anyway). There was a slogan posted with the credits that went "there is no "never". Only "not yet".

I think i saw that slogan....in the ER waiting room at Sloan Kettering

Hmmmmmmmm, any connection to the UFO-related Kettering Incident?

yes!

I don't know why anyone would presume that we are the only life form in this vast universe. Anyone who could travel here is far more intelligent than we are. There are reports of them being around our nuclear plants. We are not smart enough to keep from destroying our planet (e.g. climate change deniers), so I am sure they are afraid we will destroy their habitat. We are already leaving behind space junk. It is not enough that we are polluting this planet, we want to pollute space and other planets.

“There are reports of them being around our nuclear plants”

Some of the tightest paramilitary security patrols the inner/outer perimeter of nuclear power plants....it’s not CW! I call BS on this one

We are not alone in the universe, and never were. Humans are a work in progress. Still evolving. As a whole, we know enough to get in trouble, but not enough to get out of trouble. Some recognize cause and effect. Some can't, don't or won't and bury their heads in the sand of lies and denial. Just because I love my fellow man, it doesn't blind me to our faults.
Earth is a tiny raft floating in the sea of space. As our population grows our individual space is diminished, our resources are thinned and damage to the raft increases, bringing us ever closer to dismantling or sinking the only place, currently, that we can inhabit and survive.

Your post assumes that ETs have been here, and have some concerns about us, given the literally incomprehensible size of the universe why would they possibly care? If "they" have been here why so shy about advertising their presence ? as to governmental conspiracy theories, again why?

They are embarrassed by their teeny weenies. 🤫🤭🤭

Imagine if an alien came today and asked to be taken to our leader?

If that is the case , well ,so much for the advanced civilization argument

I would probably point at my dog as he makes me follow him around and clean up his poop and carry his water bottle.

My wife handles all inquiries.

Perhaps the government thinks the disclosure of ET would harm our belief system just as Winston Churchill said in his private letter which is available online. Also the one thing scientists believe in is every living species needs water to survive. Looking at Earth from outer space would be like viewing an oasis in a desert to them.
Also after the year 1945 when we first used nuclear weapons maybe this was seen as a threat and we must be closely monitored. Kinda of like watch out "They found the matches!"

Given the the technology to be an interstellar civilization, would they need to travel here for basic materials ? That same technology would likewise make planet earth a non threat
