Habitable Exoplanets Catalogue ranks alien worlds on suitability for life

I assume by Earthlike, they just mean it has the same ( or similar ) mass,with a temperature
allowing liquid water to exist.
Beyond that nothing is certain.
The star which the "Earthlike planet" is orbiting may be so different from the sun
that life could not exist,or many other parameters could be so different from our own
planet.

Rocky planet,with the possibility of liquid water,about the same size as Earth,is the
best hope we have ,as we know life exists on a planet just like that. Ours !

I'll bet that if we tried and were sufficiently knowledgeable, we would find about 2 dozen factors and their parameter ranges that are required for the emergence of intelligent life that we could communicate with. To start with they would have to be close to us.

I have listed several elsewhere that I feel are required. Can you all point to some of these and others. Temp range, stable orbit, circular orbit, moon to stabilize spin, Tides ?, water, land, Oxygen, outer gas giant to protect from asteroid and comet hits, magnetic field, ozone layer, several billion years old, main sequence star, non-binary star, etc

Has anyone stopped to think that if we find a planet at long range that appears to be suitable for life such a planet probably has it's own biosphere complete with life and possibly even if no communication via radio or other electronic means, intelligent life?

If such a place is found my feeling is that they should be left to their own devices and not interfered with in any way. Maybe my feelings are strongly influenced by Star Trek's prime directive and the events depicted in the movie "Avatar" but that doesn't make them any less correct.
