Earth is special not only because it has been habitable for millions of years but also because the outer part of Earth also operated geologically for hundred of millions of years -- the tectonic plates on Earth's crust gradually moved, altering the continents and seas. This movement stoked the biological evolution, the researchers say. All these factors happening anywhere else is probably as extreme rarity.
