well, our main source of energy is to boil water and use the expansion of the gas to move something
even the most efficient solar power plants are used that way (to heat up a liquid and power a turbine)
while we understand how most things work, we still don't know how to use it
and assuming that other also don't know and just use heat up liquids to power a turbine with 60-80% loss of energy to generate electricity (or that they use electricity at all) at the same time they should be able to travel thru space is naive at best

Whatever tech aliens have will work within physical laws. There's no plausible reason we couldn't understand it.

Actually I can see a point in even our own technology where we will exceed our practical limitations.
Which isn't to say we wouldn't be able to comprehend a theory of how something might work, but that the actual knowledge would rely on so much advanced detail in several fields at once that we'd end up with machines where each "part" is understood by one person, but not the others in the team. Building to a point where we could have technologies and machines that rely on machines themselves to comprehend the whole.
At least when you factor in the finite amount of learning time the average human has and their capacity to learn.
Of course we might well see a rise of technologies that allow us to expand our capacity to learn, store and access information which could then not only speed our learning but vastly extend our capacity to process data.
Imagine it you could just download kung fu on a whim

as someone from acient greece already had enough knowledge of physics to understand a steam engine and electricity
but showing him a nuclear power plant from afar, would he be able to figure out how it works and what it is supposed to do?

We can't explain where most of the universe is, cannot explain what electricity is, precisely how gravity works and great swathes of stuff connected to black holes, just for starters.
On a cosmic level we are a dumb species and making assumptions about how much we'd understand of a society that might have millennia of advancement on us is just nuts.

You're definitely moving the goalpost there but we already live in a time where we discover new forms of matter and energy that are beyond our natural senses because math says they have to be there.

I don't really see how, in response to an assertion that we'd understand something constructed by a more advanced society, pointing out a few of the long list of "known unknowns" we're aware of, let alone the many thing we're yet to discover we have no idea about, is moving the goalposts?

Didn't a wise man once say that any sufficiently advanced technology is indistinguishable from magic?
For all our scientific progress to get to our current state of understanding very little about the universe around us, there is absolutely no reason to expect that we would have the slightest chance of understanding the technology of an alien race even a century or two ahead of us.

Stars don't necessarily destroy themselves. Or at least not in a way that would destroy the surrounding material. Small stars like ours become red giants, then white dwarfs, then brown dwarfs as they cool down. This would leave a Dyson Swarm around it intact if it was built at the appropriate distance, and this process would take a long, long, long time. Nothing's forever, but if you wanted to leave a monument to your existence that other starfaring races could find, there are stars that will last long enough for this purpose.
If you really want a long-haul monument, you park it on an Iron Star (yes, on it, as Iron Stars are basically inert stellar cores of iron), and it'll last until some alien species decides to use the iron to feed their black hole farms long after the stellar formation period of the universe.

Or you instead build a Penrose sphere, basically a Dyson Sphere but around a Black Hole instead. Black Holes are going to last a heck of a lot longer than stars. Yes, technically they are different things, but close enough for comparison sake.

but if you to that we won't be able to see that sphere from earth as we cannot detect the energy difference between visible light and infared light
which makes the whole point why such a sphere is important for us obsolete

Well I said the dyson sphere was likely to be destroyed, not guaranteed. Going up to red giant status would certainly do it, unless the sphere was built outside venus' orbit. And the point is all stars die, one way or another.
And we're still completely ignoring how much material it would take to build such a sphere. Having a whole sector cleared out of solid planets would probably be more visible than the sphere itself.

Only if someone bothered to actually survey each and every system so they could go "Hey, why are there no planets in this area?", in which case they probably already found the dyson sphere just through stumbling upon it.
You can only detect planets around a distant star if their orbit happens to come between the observer and the star at the moment they are observing it, and the planet is of a certain size. So not detecting planets around a distant star is perfectly normal. Heck, we don't even know how common planets actually are outside of our own solar system.

Haha.. imagine if the grandest achievement and parting shot of the human species was a giant McDonald arches or Amazon arrow logo. Other sentient species puzzling over what it could possibly mean for the next billion years.
I liked the Peter F Hamilton idea in his Judas Unchained novel; the sphere is there not to protect or preserve something, but to keep something inside!
