Lyrics:
Verse 1
In a sealed little grain from a wandering stone,
We found five quiet letters no one wrote by hand.
Adenine, guanine—then the others in bone,
Cytosine, thymine, uracil in the sand.

Pre-Chorus
Was it chance, was it heat, was it water and time?
A chemistry whisper in the dark between.
Different mixes, same footsteps in the rhyme,
Tuned by what the rock could hold unseen.

Chorus
We’re dancing with the building blocks, drifting through the night,
An alphabet in the dust, catching starlight.
When ammonia falls, the balance shifts in view,
Old pathways, new ratios—still coming through.
From the cold to the cradle, it’s all breaking through,
Five small names saying, “Life could start from you.”

Verse 2
Two-step extraction, salt washed clean away,
Bright screens and long runs where the signals climb.
Orbiting peaks in an ion-spray,
Fragments that snap like proof in time.

Bridge
Not every route is mapped, not every shadow resolved,
Some notes below the limit, some isomers blurred.
But the pattern keeps calling—one lever involved,
A shared kind of making, shaped by what’s stirred.
And in that ancient delivery, the silence learns a word.

Final Chorus
We’re dancing with the building blocks, drifting through the night,
An alphabet in the dust, catching starlight.
Same five letters—different songs they grew,
Purines and pyrimidines changing with what came through.
From the cold to the cradle, it’s all breaking through,
Five small names saying, “Life could start from you.”
