Are we human because we gaze at the stars, or do we gaze at the stars because we are human?

A philosopher once asked, "Are we human because we gaze at the stars, or do we gaze at them because we are human?" Pointless, really..."Do the stars gaze back?" Now, that's a question.

I like the stars. It's the illusion of permanence, I think. I mean, they're always flaring up and caving in and going out. But from here, I can pretend...I can pretend that things last. I can pretend that lives last longer than moments. Gods come, and gods go. Mortals flicker and flash and fade. Worlds don't last; and stars and galaxies are transient, fleeting things that twinkle like fireflies and vanish into cold and dust. But I can pretend...

Now there were stars overhead, hanging like frozen spears of light, stabbing the night sky.

Praise the dirt you walk on and the stars you gaze upon.

Idris: Are all people like this?
The Doctor: Like what?
Idris: So much bigger on the inside.
