Mathematically, the probability is other advance civilizations should exist, though that chance is infinitesimally small.
IF aliens are here, the tech required for that visit is not generations away from what we have, it millennia away. There would be nothing any country could do to ‘defend’ against them. No more so than a dog could defeat an F-16.

The distances are too great they’re not folding space yet the spice is not been discovered. So I’m going to say they are traveling in the fourth dimension from the future of this Earth or maybe from the past.
Science fiction writers have been all over this for the last 50 years.
Considering that the last estimated age of the universe is 26.7 billion years old and there are an estimated 200 billion galaxies in the observable universe, there is a very good chance that there just may be life out there that is thousands of years ahead of us in technology that we can't even imagine.
Case in point, look how far technology has advanced in just the past 100 years and imagine what may be discovered in the next 100 to 200 years....
The “story” behind Roswell, is that the UFO crashed because of a then-new powerful pulsed Raytheon radar system out of the nearby Holloman AFB. There were no flight controls on the craft that we would recognize as such, it was done telepathically.
Please don’t take it to mean my recounting of the tale indicates I believe it, just that is the story.
