Maybe the defining quality of being human is searching for the meaning of life.
Only humans search for the meaning of life and that is what defines us.
We seek comfort in a universe filled with a vast space that is not known.
Humans seek for answers through religion, music, art, science, but even with all that… humans do not know the full picture.
Humans are living lives with a blindfold on, hoping that life really does mean something.
We, humans, are just lost souls who wander the world for an answer.
