Ancient astronaut theorists argue that Malta's megalithic temples, among the oldest stone structures on Earth at 5,600 years old, may conceal evidence of extraterrestrial contact far earlier than mainstream archaeology acknowledges. The episode focuses on mysterious "cart ruts"—grooves carved into Malta's limestone bedrock—that extend as much as 140 feet below current sea levels in the Mediterranean. Researchers like Robert Schoch suggest these ruts could only have been created when sea levels were lower, potentially dating them to before the last ice age ended around 12,000 years ago—thousands of years before the Sumerian civilization and long before Malta's known megalithic builders disappeared around 3,000 years ago. The episode also highlights discoveries of elongated skulls in underground complexes, which some theorists interpret as evidence of "giant hybrid beings" created through alien intervention.
Mainstream archaeologists date Malta's temples using radiocarbon analysis and attribute the cart ruts to erosion from ancient wheeled vehicles on soft limestone, though the civilization that created them remains poorly understood and seemingly vanished abruptly from the archaeological record. The genuine mystery here—why a sophisticated temple-building culture left no clear descendants and how cart ruts came to be submerged at such depths—offers compelling questions even for skeptics. Whether the answer involves post-ice age sea level rises (a documented geological phenomenon) or something more exotic, Malta's concentration of advanced Neolithic construction on such a tiny, strategically located archipelago presents real archaeological puzzles worth examining.
Bent Pyramid of Dahshur
Egypt · Ancient Egyptian
Ancient Aliens suggests the Bent Pyramid's unique angle change and internal chambers indicate experimental construction possibly guided by extraterrestrial architects. The show proposes the pyramid's unusual design reflects advanced knowledge of structural engineering unknown to Ancient Egyptians.
Luxor Temple
Egypt · Ancient Egyptian
Ancient Aliens proposes that Luxor Temple's precise astronomical alignments and architectural sophistication indicate extraterrestrial input into Egyptian civilization. The show suggests the temple's geometric perfection and alignment to celestial bodies demonstrate knowledge beyond what Ancient Egyptians allegedly possessed.
Meroë Pyramids
Sudan · Kushite / Meroitic
Ancient Aliens suggests the Meroë pyramids' numerous quantity, geometric precision, and African location indicate extraterrestrial influence on Nubian civilization or represent an alien base. The show questions how African cultures achieved such sophisticated pyramid technology independently.
Red Pyramid of Dahshur
Egypt · Ancient Egyptian
Ancient Aliens proposes the Red Pyramid's structural perfection and internal precision indicate extraterrestrial architectural guidance, suggesting it represents a refinement of pyramid technology possibly influenced by alien contact. The show questions how Ancient Egyptians achieved such geometric accuracy without external knowledge.
Shipton's Arch
China · Chinese
Ancient Aliens suggests Shipton's Arch's massive scale, remote location, and unexplained purpose indicate possible extraterrestrial involvement or ancient advanced engineering knowledge. The show questions how ancient peoples could construct such a massive natural stone arch without modern technology.
