How rare is our Solar System? The Mechanics and stable orbits of our solar system defy the norm. Our sun (Sol system) looks perfect in this computer generated video of 1,705 worlds in crazy orbits around 685 distant stars. All discovered by the Kepler exo planet Telescope.

Recent study eliminates prior Habitable zone of orbit for a planet by 66 %!
Schwieterman said that "showing how rare and special our planet is only enhances the case for protecting it. As far as we know, Earth is the only planet in the universe that can sustain human life.”
"But we can say that it is becoming increasingly likely that the percentage of exoplanets that could support complex life as we know it is very small indeed." https://astrobiology.nasa.gov/news/exoplanets-with-complex-life-may-be-very-rare-even-in-their-habitable-zones/
Due to the exhaustive efforts of searching 60 yrs for ET and coming up with 0 results via conventional thinking. The best and brightest of Mankind are now thinking un-conventional and searching for space alien Mega-Structure Dyson Spheres.
Using a satellite called Gaia, ESA Scientists are looking for dimming or slowly disappearing stars surrounded by a Dyson sphere. To date after 1.7 billion stars checked. The results are 0 found! Our Galaxy has NO Dyson spheres. Still early in the Qwest for Mega-Structure Dyson objects after all we do have the entire Universe left to scan.
"With 1.7 billion objects surveyed in the latest data release, Gaia could reveal Dyson spheres that are under construction. By correlating with other infrared observatories, it could even potentially find completed Dyson spheres that were radiating enough energy. At the time of this publication, though, the full suite of data we have indicates exactly zero Dyson spheres in the Milky Way." forbes.com/sites/startswithabang/2018/05/03/dyson-spheres-the-ultimate-alien-megastructures-are-missing-from-the-galaxy/#5dbdf6763138
