We live on a blue planet
that circles around a ball of fire
next to a moon that moves the sea,
and you don’t believe in miracles?
Earth, also called the world and, less frequently, Gaia is the third planet from the Sun, the densest planet
in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical
object known to accommodate life.
The earliest life on Earth arose at least 3.5 billion years ago. Earth's biodiversity has expanded continually
except when interrupted by mass extinctions. Although scholars estimate that over 99 percent of all species
that ever lived on the planet are extinct, Earth is currently home to 10–14 million species of life, including
over 7.3 billion humans who depend upon its biosphere and minerals.
