I want to share with you the speech of Neil deGrasse Tyson, a famous astrophysicist, that appears in the song 'Exist' by the band Avenged Sevenfold, from their album 'The Stage'. Since in this album are treated scientifically and philosophically themes like human existence, religion, and how our humanity can be projected in the future and in the universe, if you like their musical genre (rock), I recommend you listen to it. Anyway, following the interesting scientist's talk:

“We have one collective hope: the Earth.
And yet, uncounted people remain hopeless, famine and calamity abound.
Sufferers curl themselves into the arms of war;
people kill and get killed in the name of someone else’s concept of God.
Do we admit that our thoughts and behaviors spring from a belief that the world revolves around us?
Each fabricated conflict, self-murdering bomb, vanished airplane,
every fictionalized dictator, biased or partisan, and wayward son,
are part of the curtains of society’s racial, ethnic, religious, national,
and cultural conflicts, and you find the human ego turning the knobs and pulling the levers.
When I track the orbits of asteroids, comets, and planets,
each one a pirouetting dancer in a cosmic ballet, choreographed by the forces of gravity,
I see beyond the plight of humans.
I see a universe ever-expanding,
with its galaxies embedded within the ever-stretching four-dimensional fabric of space and time.
However big our world is, our hearts, our minds, our outsize atlases, the universe is even bigger.
There are more stars in the universe than grains of sand on the world’s
beaches, more stars in the universe than seconds of time that have passed since Earth formed,
more stars than words & sounds ever uttered by all humans who have ever lived.
The day we cease the exploration of the cosmos is the day we threaten the continuing of our species.
In that bleak world, arms-bearing,
resource-hungry people & nations would be prone to act on their low-contracted prejudices,
and would have seen the last gasp of human enlightenment.
Until the rise of a visionary new culture that once again embraces the cosmic perspective;
a perspective in which we are one, fitting neither above nor below, but within.”

Neil deGrasse Tyson
