In 2050, 30 years after its discovery, the mysterious half-carved stone was taken from its far orbit and brought to the Earth. Even the wisest still don’t know if it’s a product of nature or alien made. Is nature able to create this smooth surface and regular shape? Obviously yes, and even more complex geometries we can find in Earth. Nobody can imagine what's outside. However something else was carved on this asteroid. Maybe random. Biologists, religious and philosophers debate about the weird symbols found on the surface:
1.) A triangle.
2.) our rods with look like a four digits abacus.
3.) A kind of stain.
