Arbitrary

Sun gives us light.
The red gleaming ball of pure energy.
It seems small for us,but it has a huge influence on our life.
It is one of a billion of suns.
Earth gives us life.
The blue planet somewhere in the universe.
The cold surface and the hot core give us life.
The distance to the sun makes it possible,
the sheer hazard of physical coherence.
Meeting someone,
liking someone,
feeling something for someone...

Is it also physical coherence?
Is it destiny?
Is it the simple goal of propagation?
