"I don't know" does in deed turn out to be one the hardest things for any of us to say.

With the current clampdowns and bans following this little contretemps... there's a little bit less internet love for crackpots at the moment. Maybe your wife could look into joining something else.

Why do you need 'internet love'??

Dont you really really want it to be so??

Well it is "SO" but many many peeps want it to be "NOT SO". They hunger 'not to be alone'. I suppose they are inherently lonely. ?

Unless there is already a "galactic governing body" of some sort waiting for us to get to a certain level before they introduce themselves, I see only a couple of choices left.

If there was an "Independence Day" type species, we probably wouldn't be here anymore.

Or there is nothing but us. Or perhaps it is so rare, and long distance space travel so impossible, that we'll never know.

I don't see many other possibilities.

In, fact, I don’t even know if there is anything “unknowable” (wouldn’t it be a paradox, to know of something unknowable?).
"what I do not know I do not think I know", often paraphrased as "I know that I know nothing." ~ the Socratic Paradox, from Plato

Would that Tolstoy were right:
“The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of a doubt, what is laid before him.” ~ Leo Tolstoy
Jose Ortega y Gasset delved into this in his "History as a system".

I don't "believe" or disbelieve anything not adequately proven. With a sample size of one and a profound ignorance about an incomprehensibly vast universe, it's just not possible to form a reasonable opinion.

People sometimes forget that we're not obligated to pick sides. To paraphrase Red Green, it's OK to say those three little words men hate to say: "I don't Know."

That said, in the face of uncertainty one can only play the odds. The odds are pretty good that this little speck we inhabit is not unique in the universe.
not unique means there are comparable earths with life . So do you wish "not to be alone"? Is that your desire?

As relevant as how to tie a monkey fist or bantering about composting toilets versus using pump out system (or a plain old bucket) .... but do the aliens appreciate sailing as a mode of transportation or an activity. Boating requires a romantic affinity for the water. Sailing brings out the poet, the dreamer, the adventurer in each of us. Why the hell do it otherwise? It is slower, more expensive and more cumbersome than most other modes of travel. Yet here we are, each of us loving boat cruising enough to subscribe to a site where we can wax nostalgic and trade knowledge about the subject as the winter stove shines a cherry red glow on the wall through the early evening twilight. I think the real question is do aliens have the capacity to appreciate boating? Cause if they do, we have more competition for the prime anchorage spots.
Wouldnt be just dandy if a tiny lil ufo with some tiny greys landed on your foredeck and started dancing? Would you record them on your iphone?

My pet notion is that all we need to do is get as close to C as physically possible, then use quantum tunneling to simply skip over the speed of light.

Maybe all we need is a really big sail .
If it is impossible then how do you know it goes infinity? How can we know the results of something "impossible" if it cannot occur?
