In the year 2147, Earth had long exhausted its resources. Humanity's last hope lay in the stars, specifically on Andara-6, a lush exoplanet discovered 12 light-years away. The first human colony, Astra-1, was established with a crew of 30 scientists, engineers, and explorers. Among them was Dr. Leila Tran, a xenobiologist with a fascination for alien ecosystems.

Leila was the first to notice the echoes - whispers that drifted through the jungle at dusk, unintelligible but rhythmic, like language wrapped in wind. The others dismissed it as atmospheric interference. But Leila knew better. Plants on Andara-6 glowed in response to sound. Patterns emerged. She recorded the whispers and ran them through linguistic AI.

To her astonishment, the patterns matched the syntax of early human languages - Sumerian, Egyptian, even Morse code. It was as if the planet itself was speaking to them.

One night, following the echoes deep into the forest, Leila discovered a grove of crystalline structures pulsing with light and sound. The whispers grew clearer: "We remember you."

She touched one crystal. Visions flooded her mind - memories of Earth, ancient civilizations, stars being born. The Andaran biosphere was not just alive; it was conscious. And it had been watching Earth for millennia.

Leila returned to Astra-1, forever changed. Humanity hadn't found a new home. They had rediscovered an old friend.
