So many times greats like Heinlein and Silverberg have written
about us going to exoplanets, and it being like Earth.
Sorry,,,, NO!

 Plate Tectonics Might Only Occur on 0.003% of Planets. That Makes Earth Very Special Indeed.
Plate tectonics, oceans, and continents might just be the secret ingredients for complex life on Earth. And if these geological features are rare elsewhere in the universe, then perhaps that explains why we haven’t yet discovered intelligent alien life. New research from American and Swiss Earth scientists suggests that these ingredients represent missing variables in the famous Drake equation, devised more than half a century ago to estimate the chances of finding advanced civilizations in our galaxy. Including these new variables could completely rewrite the probability of detecting intelligent life in the Milky Way.
 Go to the citation for the rest ----.

Life is likely everywhere liquid water is found but it won't
be necessarily intelligent or complex.  Remember that a Mars-sized
planet had to hit the earth to create the Moon. When it did that
it may have kicked up the abyssal ancient prokaryotic cells which
on finding themselves in a very strange environment formed the
bacterial mats which led to the first great extinction by producing oxygen.
Without the higher biological energies produced and enabled
by the presence of Oxygen we might not have gotten far enough to
spoil it with tailpipe emissions.
Not to mention the presence of the Moon which with its tides
may have given rise to life on land.
I think PBS has one show or series entitled "Disaster Planet"
and without disasters we might not have grown, an overly large perhaps,
brain.
