Of course, but we still cannot find such. In the foreseeable future, we will only be able to find planets like the Earth and determine their oxygen atmospheres. When observing from interstellar distances, it is possible to detect only a civilization not lower than the level of development of the middle of the 20th century - when television appears and, accordingly, the planet begins to "glow" in the microwave range.

Given the age of the Universe, the age of most of the observed stars, and therefore not very observable planets, it is highly likely that the very same Ancient-Highly-Developed-Mighty-Civilization-Which-Mysterious-Disappeared-Leaving-After-Itself-High-tech -Artifacts are us.

That's right. Everything indicates that if life exists somewhere besides the Earth, then it is unlikely that it originated and developed there earlier than on Earth. And certainly nowhere could life have arisen so long ago that the local civilization would have already reached some super-technological level of development. At best, if we are talking about brothers in mind, they colonize their solar system. At worst, another form of life is so different that their high-tech development goes in a completely different direction, and we will never know about each other's existence.

The pyramids were built 4500 years ago; on a cosmic scale, this is zilch. Because even between the stars, a flight at light speed takes tens of years.

And yes, there is no common single time, because if we find a civilization building pyramids, a signal will bring us their distant past, and what happens there just not available in any way right now.

First of all, it is worth noting that in the light of our level of technological development, our chances of intersecting with a civilization that is just beginning its path (if it starts its path in any way similar to us) tend to zero. We will not find them corny. Means for contact with civilization, which can itself "reach out" to us, can at least be found here.

That is, they are discussing a more realistic perspective at the moment.
