Where do we come from? How was the world around us formed?

Powerful engines of reflection, these questions answer a visceral need to know our origins, our belonging and to understand this world around us.

Our planet, the Earth, is a planet similar to the others. Like the others, it is unique. The planets share a part of their history but have then evolved differently developing their own individualities. The Earth is the only planet known to harbor life. Among all the organisms that have succeeded each other, one of them has demonstrated a strong capacity to master its environment and adapt it to its needs: Man.

Man hates ignorance. He therefore started to study these questions very early on in order to understand the Earth. But can we really claim to know the Earth when so many interpretations and uncertainties come into play? Man studies the subject, first through philosophy, then through geology. The study of the lithosphere reveals an astonishing amount of information allowing us to go back to its formation. Today, a history of the Earth since its birth is written, but the scenario is not fixed and will continue to evolve with the discoveries. Its appearance has not always been that of the beautiful, calm and peaceful blue planet. Its birth and its "early childhood" took place in chaos, an unprecedented hell in which unimaginable heat reigns.

How did it evolve to become the Earth as we know it today?
