Earth is incredibly unique, but there are over 200 billion solar systems just in our galaxy.
That makes another planet in the universe very similar quite likely, but not to an exact.
First, the solar system would have to have formed much the same, the planet composed of similar elements.
The presence of water dominating the surface. The composition of its atmosphere nearly the same. The early development of vegetation much the same, and the seeding of some form of life with little room for variation.
This planet would need volcanic activity with a similar molten core of nickle/iron. Even then, it would need a similar impact of asteroids to instigate this core to spin relative to the planet so as to have a suitable magnetosphere.
Limits on its tilt of axis to its ecliptic. A little flexibility to its own AU but not much.
So you have an idea just how rare earth is and why no exactness between any two planets.
>>Possible,,just not too likely,,and would be at such distance, we will never know of its existence.
Habitable planets, even some form of life nearly has to exist given the vast number 'out there'.
