Two and a half miles beneath the Pacific Ocean is total darkness.

No sunlight reaches there. No plants grow there.

So when oxygen sensors on the ocean floor came back positive,

the scientists thought it was an equipment failure.

They tried again. Same result.

Oxygen was being created not by plants or sea life.

It was coming from rocks.

Ancient metallic rocks that generate electricity.

They produce enough current to split water molecules into hydrogen and oxygen.

They called it dark oxygen.

This changes everything we know about the Earth's early atmosphere,

and about the evolution of life, and about where we might find alien life.

In 2024, the dark oxygen study stunned the scientific community.

Researchers from dozens of fields and hundreds of organizations scrambled to understand the implications.

But one organization wasn't surprised. They've known about these electric rocks since the 1960s.

They even mined them in the 1970s. that organization is the CIA.

The Clarion Clipperton Zone, or CCZ, looks like an underwater desert. It stretches across 1.7 million square miles of the Pacific.

It's bigger than India, almost two miles down.

Cold, dark, pressure that would crush any living organism.

Or so we thought.

In 1968, a Soviet submarine carrying nuclear missiles sank in the

Pacific. The Soviets couldn't find it. The U.S. government wanted that sub. The CIA launched
