The Rock That Was There Before the Sun

You are holding a piece of the oldest thing you will ever touch. It is dark, crumbly, and it smells faintly of something — sulfur, maybe, or something older than sulfur, something with no name because nothing was alive yet to name it. This rock was not made here. It was assembled in the cold dark far beyond Mars, grain by grain, before the Earth existed, before the Sun had fully switched itself on. And somehow it arrived. Most of it burned. But some did not.

Scientists call them carbonaceous chondrites, and what they carry inside is almost too much to absorb. Water — locked into the crystal lattice of their minerals, water that became your oceans. Amino acids — the same building blocks your body uses right now, pre-assembled in interstellar space by no one at all. Not life. But the ingredients. Left in a box on the doorstep.

The rock doesn't look like a delivery. It looks like a smudge. It looks like nothing. But every ocean you have ever seen, every glass of water you have ever swallowed, began as ice on the outside of a pebble drifting between the stars, waiting for somewhere to land.

And the question nobody has fully answered yet: did every rocky planet in every solar system get the same delivery?
