a miracle in the universe, appeared around 4 billion years ago.
And we humans only 200,000 years ago.
Yet we have succeeded in disrupting thebalance so essential to life.
Listen carefully to this extraordinary story, which is yours,
and decide what you want to do with it.
These are traces of our origins.
At the beginning, our planetwas no more than a chaos of fire,
a cloud of agglutinated dust particles,
like so many similar clusters in the universe.
Yet this is where the Listen to me, please.
miracle of life occurred.
Today,life, our life,
is just a link in a chain of innumerable living beings
that have succeeded one another on Earth over nearly 4 billion years.
And even today,
new volcanoes continue to sculpt ourlandscapes.
They offer a glimpse of what our Earth was like at its birth,
molten rock surging from the depths,
solidifying, cracking, blistering or spreading in a thin crust,
before falling dormantfor a time.
These wreathes of smoke curling from the bowels of the Earth
bear witness to the Earth's original atmosphere.
An atmosphere devoid of oxygen.
A dense atmosphere, thick with watervapor,
full of carbon dioxide.
The Earth cooled.
The water vapor condensed and fell in torrential downpours.
At the right distance from the sun, not too far, not too near,
the Earth'sperfect balance enabled it to conserve water
in liquid form.
The water cut channels.
They are like the veins of a body, the branches of a tree,
the vessels of the sap that the water gave to theEarth.
The rivers tore minerals from rocks, adding them to the oceans' freshwater.
And the oceans became heavy with salt.
Where do we come from?
Where did life first spark into being?
A miracle oftime,
primitive life forms still exist in the globe's hot springs.
They give them their colors. They're called archeobacteria.
They all feed off the Earth's heat.
All except the cyanobacteria,
