Earth, we think. This is sometimes a point of dispute.
As of now, there is no definitive evidence or consensus within the scientific community about the existence of intelligent life on other planets. While many scientists believe that it is possible, no confirmatory discoveries have been made. The search for extraterrestrial intelligence continues through initiatives like the Search for Extraterrestrial Intelligence (SETI) program.
There is no "second smartest" planet in the solar system. By a stretch, Earth may be regarded as the "smartest" due to the presence of intelligent life. However, since it appears that no other planets in the solar system have life, they are all equally "not smart."
This quote is commonly attributed to physicist and astrobiologist Carl Sagan. Sagan used this quote to reflect on the vastness of the universe and the potential for intelligent life beyond Earth.

Yes, it is the only planet found so far.
Originating, located, or occurring outside Earth or its atmosphere: intelligent extraterrestrial life Originating, located, or occurring outside Earth or its atmosphere: intelligent extraterrestrial life
Until further proof, an atmosphere that can produce and support intelligent life
None (intelligent or otherwise) has been positively identified except on Earth.
"Other" intelligent life? I think we have yet to prove that there is ANY intelligent life on our planet. There was a button to improve the answer but this answer requires no improving. From the smallest cell in our diverse bio system things tend to work together for survival. Now when we think of intelligent life we like to think humans but really we don't work for our complex bio system, instead we pollute, and kill, and change. more like a complex virus but far from intelligent
Of course. ___________________ ...no intelligent life that Spock and I have ever observed. Scotty-- beam us up. Look around you...
It is the only place in the known universe that has been verified to contain intelligent life.
