Little by little the land surface
became cold and
changed into a rocky crust

A burning material, called magma,
remained in the deepness of the earth

A huge pressure from the inner part of the planet pulled out and created the volcanoes from which an enormous quantity of gases and vapours came out forming the atmosphere

These vapours started condensing and creating huge clouds

The clouds originated  the rains that, throughout the years,
filled the large valleys creating the oceans and the seas

In the oceans and seas, about 3,5 milliards of years ago, the first forms of life were born (protocells)
which originated animal and vegetable life on our planet

Since then, life was born on our planet, expressing itself in a variety of forms and shapes.
Through the millenniums, life changed and evolved into more complex
types of life: the man
