I have always found subjects such as this interesting...
IMO, as any species begins to evolve it will reach a point where
instinct is overtaken by intelligence. This is an important hurdle,
especially if you take us as an example.
To me it seems like God's chess game.
If any life form can evolve and successfully cede survivalist instinct
to moral intelligence BEFORE they use up their available resources,
or foul their habitat to toxic limits, or annihilate themselves thru war...
then God wins. We Humans are at this critical juncture right now.
Now back to topic...
An alien civilization 100,000 years beyond our current age of technology
that survived this transition?
To make a comparison, imagine traveling just 1,000 years into our recent
past with present day technology. No army (then) on earth, would be able to
stand against a well-equipped, modern platoon. A box full of gadgets, such
as pens, lighters, watches etc, would fetch a king's ransom. In short what
we could do would appear as magic to our ancestors. And we have
accomplished this in 1/100 of the time you are referring to.
I would say the chances of encountering an alien species FAR in advance
of our technology is much more likely than encountering one anywhere near
our current stage of technology...and that is an understatement.
I would expect that any alien species 100,000 years in advance of us
could (and probably would) completely conceal themselves from our
scrutiny IF they decided to visit. I can see no clear reason why we should
fear, owing to my assumption that if they made it thru their own transition
from instinct to intellect, aggression would be a receding
quality of their culture.
In fact, I see no reason why they would make contact at all. If the Earth
had resources they needed, it is much more likely that they have already
visited our planet tens of thousand of years ago and taken them.
My greatest fear is that an advanced alien species would
see us as mere animals, much the same way we see horses and cows,
and would either view us as potential laborers, or as a source of
But I find it more likely, that they would see us as a curiosity, something
to be studied and watched...at least until the time that we have (hopefully)
made it thru our transition from instinct to intellect.
Until then, perhaps they will watch and occasionally reveal a little
of themselves to us as an amusement. Much the same way we tease
a cat with a lazed-pen.
I think I could type a book on this subject without getting bored, but
I'll leave it at that.
