Shimrod, I'll answer those questions you had:

"why have the aliens only revealed themselves to ordinary Americans and Canadians who have usually been travelling at night on country roads when the encounters occurred?"

Absolutely not so! Things that appeared to quite possibly be alien craft, and which were interpreted as probably being alien craft, have been seen by people in all walks of life including several heads of state (Jimmy Carter, for one, a South American president for another, and it doesn't end there), numerous politicians, civil airline pilots, military pilots and other military personnel, doctors, lawyers, police officers, a very large part of the population of some entire cities (such as Phoenix Arizona), civic officials (such as the mayor of Phoenix), etc...ad infinitum. It is nothing but a hilarious cliche and an often repeated piece of mythology (or else a deliberate lie) that no one sees "UFOs" except "ordinary Americans and Canadians who are travelling at night on country roads". Total bullshit...and, frankly, one has to wonder who was the turkey or the agent provocateur who concocted that ridiculous myth in the first place? Who disseminate it?   And what in the world gave him the idea that there was any basis to it...because there isn't. UFOs have been seen in every country on Earth, they have been seen by both day and night, by every sort of person, and they are not a strictly American/Canadian phenomenon. There are some South American locales where they have been seen so often that the local government there has put signs up on the roads designating the area as a UFO sighthing area (a bit like the signs you put up to warn of deer or moose crossings). The Mexican air force has pursued and filmed UFOs over central Mexico. You are living in a fantastic thought bubble of your own (or someone else's) devising if you think that your question above has any relevance to the actual situation regarding UFO sightings on planet Earth.


Your other question was: "And why have such auspicious encounters been free of any lasting consequences for the rest of us?"

Now THAT is an intriguing question, and one well worth asking! Yes, indeed. I regard it as a virtual certainty, given the number of recorded incidents and the other evidence that has accumulated by now, that aliens have been visiting us....and it does appear that it hasn't had lasting consequences for most of us (as far as you or I know). That's VERY interesting indeed! What does it suggest? It suggests that they don't act as we would act. Because we are ruthless exploiters. When we discover a New World (as Columbus and the Conquistadors did), we invade it, we exploit the crap out of it, we wipe out or dominate the indigenous people, hunt down the animals, cut down the forests, dig up the land, and so on. We are pillagers, wasters, and despoilers, intent on profit and dominion.

If we were dealing with aliens who were the kind of cultural barbarians we are, it would all be over for us by now, in my opinion.

We are probably dealing with someone who is quite unlike us. That is, they may have a far more developed sense of both morality and responsibility than the human race presently does. They may regard it as wrong to invade, exploit, and dominate other races...but not wrong to observe them. If so, it would behoove us to stop fighting idiotic wars with one another and learn something useful from these visitors that could help us move out of early adolescence and into adulthood.

Perhaps you have to reach adulthood before you can develp the kind of technology to do really effective and fast space travel. It might even be a fail-safe mechanism built into the very chain of evolution. ;-)

If so, it could prove quite handy, I think. I'll put it bluntly: If we were them, we would devastate this planet. Let's bloody well hope they are not anything like US.

And yet another possibility: They may not really need anything we have here...but they may still find us quite interesting to observe, simply as a way of adding to their knowledge about other lifeforms.

And yet another possibility: They may consider us to be their distant relatives or their spiritual brothers and sisters, and they may be concerned about the great danger we are putting ourselves in by our own destructive behaviour on this planet. If so, they could be attempting to make some sort of useful contact with our governments in order to help us in some way. Now...if our governments preferred to maintain the status quo as is...that status quo being based on our governments being seen as the ultimate and unchallengable power on this planet, and seen as having the answer to everything, and seen as our protectors rather than our dominators...then our governments might want anything BUT the general public getting any wind of such a situation at all. They might do a great deal to suppress what information they have and to avoid open contact or public recognition of what is happening.

Those are all possibilities. I don't necessarily espouse any one of them, I'm just saying those ARE among the possibilities suggested by alien visitors who do NOT interfere with us much at all.

And then there's the ONE possibility you clearly favour: No aliens at all. No alien vehicles. Nobody who has mastered distant and speedy space travel. Nobody around but us. No government coverup. Just a bunch of confused ordinary Americans and Canadians driving around on country roads at night and having hallucinations or not knowing what they were looking at. ;-) What a simple and comforting thought to hold to one's bosom! ;-D
