declining birth rates, many including USA below replacement.

Rather write a long rant on the topic, I think you'll find this video
more digestible.
"The World Population Crisis NO ONE Sees Coming"
<https://www.youtube.com/watch?v=tk5KoWUwz6Q>  (21:52)
The part on the changing demographics is rather interesting.  Note
that the author of the video made no attempt to predict the future or
even propose a short term trend.  When there were benefits to having
many children, birth rate and fertility increase.  When the benefits
are less valuable or useful, as is currently the situation, birth rate
and fertility decrease.  What happens when the aliens arrive is
unknown.  If they are hostile, increasing the birth rate is what
traditionally is used to build a large army to fight the aliens.  If
they are friendly and help solve our problems, people might think that
it's a wonderful world and a great time to have kids. Or, they might
decide to have a good time and not want to deal with difficulties of
raising kids.  Toss a coin on that one.

Chairman Mao's one child policy was a resounding success, but not in
the manner initially intended.  What it actually did was produce a
radical change in China's economic policies and opened China to trade,
commerce and a restricted form of private enterprise. It didn't
change China's political system in the slightest.  The result was a
spectacular increase in the standard of living.  The birth rate is now
decreasing because the population have found better things to do than
raise large families.  It took a while longer than Mao would have
predicted, but I think if he were alive today, he would be proud of
what he indirectly accomplished.

IMHO it's more likely than not that there is other life
beyond Earth. But, given the immense distances, highly
unlikely that any two civilizations capable of leaving their
own planet would ever encounter one another.

True.  However, there are plenty of other things in our environment
and in the cosmos that have very low probabilities.  For example, the
numerical values of the physical constants control so many things that
are responsible for making our universe and ourselves that suggest
intelligent design rather than random chance is what sets their
values:
<https://en.wikipedia.org/wiki/Physical_constant>
Change any of these even slightly and our universe will fall apart.

And a further thought- One of my pet peeves is the comment
in NASA press releases about exoplanets which 'could support
life'. pfffft, how parochial and narrow minded.  There's no
reason to limit a 'life form' to compatibility with human
respiration of our atmosphere, our operating temperature
range or more importantly our chemistry. It's not
unreasonable to posit an utterly different basis for life
outside of carbon chemistry.

I beg to partially differ.  If we assume that all the known elements
are present in roughly the same distributions throughout the universe,
there's a good chance that self-replicating life processes will be
built using the same elements as on planet Earth.  "Carbon atoms are
unique because they can bond together to form very long, durable
chains that can have branches or rings of various sizes and often
contain thousands of carbon atoms."
<https://www.nature.com/articles/139290a0.pdf>
The emergence of life is possible with comparatively inferior elements
but the main building block will mostly likely be a stable atom that
will build the strongest and move versatile bonds to other atoms.

That's from our extremely biased perspective. To limit the possibility to life as we know it simply due t the fact that that's what we know is - as Andrew notes - myopic at best.

All random thoughts above are fact-free, non disprovable and

Today's science is no long built on truths, facts and certainty.  It's
built on probability.  There have been many major discoveries that
were built on guesses, hunches, low probabilities, thought
experiments, casual observation, wishful thinking, etc. It's no
longer possible to judge something as being right or wrong.  There is
a huge gray area between right and wrong that is currently the source
material for what we call science.  Throw relativity into the puzzle
and everything becomes a probability.  There's no need to apologize.
