Only the strongest will survive.

Upon the rubble and ashes of the old,
New civilisations arise.
The death of one is the birth of another,
Life is an infinite circle with no beginning, no end.

Wars end... but not really.
They simply morph into new conflicts,
Distant arguments in faraway lands,
Struggles for dominance leading to other wars.

There are billions of us today, however,
By our own doing, more people die in a day than are born on this planet,
A trend that might become irreversible unless we break the vicious circle.

We're not wise enough to do that, though.

Now they are only watching.
But when the right time will come,
They'll approach to finish our self-inflicted destruction, and do what we failed to do,
Save the planet we ruined, in their own way.

And then, at the dawn of the new civilisation,
Who will wipe out the memory of the previous to start with a clean slate,
Only a handful of the strongest of those still standing will survive.

Maybe. Maybe not even them.
