Light from the sun created the first eye.
Millions, perhaps billions, of years ago,
A creature evolved a light sensitive set of cells,
And so emerged from sightlessness.
This creature had an advantage over its blind competitors,
Which led to the breeding of offspring with the same mutation.
So it was the lit world became visible.
Let there be light also meant seeing the light,
Not just groping in the dark.
So, now, millions, perhaps billions, of years later,
Many creatures are endowed with highly evolved eyes —
Eyes that, furthermore, can see deep into the universe with telescopes
Or deep into the once invisible, microscopic world with microscopes.
Our vision has become transcendent over time,
One of the great achievements of the species on Earth,
Having evolved from a brutish, dark world
Where there was light, but no sight.
