Stardust Echoes!

In 2387 AD, human civilization has expanded to 17 galaxies in the Orion Arm of the Milky Way, and the total population exceeded 80 billion. Faster-than-light navigation relies on "folding doors" - using quantum entanglement to achieve space jumps, but they can only lead to known coordinates. In 2341, humans discovered the first echo tablet under the ground on Mars. The inscription revealed: "You are not native to this place. You were sown." Human genes come from an ancient civilization called the "Sowers." This discovery, known as the "origin shock," triggered religious collapse, philosophical reconstruction, and political turmoil. Some see it as a miracle, some as a conspiracy, and some as evidence of evolution.
