In 2187, humans have been able to achieve cross-planet archaeology, but there are still three major gaps in the understanding of "human origins" -
- "Prehistoric civilization gap": There is a lack of key evolutionary evidence between the "Lucy fossil" in Africa 3 million years ago and the "Homo sapiens explosion" 100,000 years ago;
- "Extraterrestrial related faults": The suspected artificial excavation traces found on the back side of the moon and the Utopia Plain on Mars cannot be connected with the evolution line of earth's civilization;
- "Symbol inheritance gap": Similar symbols in Neolithic sites around the world (such as Liangzhu in China and Sumer in Mesopotamia) cannot find a common origin.
The "Civilization Decoding Bureau" has been established around the world, bringing together scholars from multiple fields to form a "Decoding Team" to solve the ultimate mystery of human origins through cross-planet archeology and interdisciplinary textual research. However, during the research process, the ideological conflict between the "traditional evolutionists" (who insist on independent human evolution and deny extraterrestrial intervention) and the "interstellar connectionists" (who believe that the origin of human beings is related to extraterrestrial civilization) continues to intensify, and some key evidence frequently "mysteriously disappears", and there seems to be interference from unknown forces behind it.
