Aliens B.C. (S10E01)

Vast artificial caverns... Enigmatic edifices... And submerged findings that upend our understanding of history... Could it be true that an advanced society thrived on Earth millennia ago? Were these inhabitants human, or perhaps extraterrestrial? Contemporary archaeologists are persistently discovering relics and locations that challenge the established timeline of human existence. Across the globe, we encounter monumental stone structures linked to enigmatic ancestors, peculiar humanoid sculptures from pre-history, and signs of ancient subterranean dwellings carved from solid rock. Is it possible that a sophisticated civilization existed far earlier than we assume? Might the tales of a time when deities and alien beings roamed our planet hold more truth than mere legend?
