Life, particularly when it defies gravity, by walking upright and committing levitation, is doing the nearly impossible, not the easy, but the difficult, like doing the kennedyesque going to the moon.
The universe's origin, start, by separating matter (gravity) from energy ( not a null sum but 2 sum entity) and life, disrupting successfully the race to entropy, have the mark of a driving force, a master worker perhaps.
