In the rugged hills of South Africa's Mpumalanga region, a chance catastrophe in 2003 unveiled what could be humanity's most ancient enigma: pilot Johan Heine's plane plummeted from the sky, crashing into a remote mountainside where he miraculously survived to stumble upon towering dolomite monoliths and a vast stone circle emerging from the earth like forgotten sentinels of a lost era.

Dubbed Adam's Calendar for its staggering antiquity - potentially dating back 300,000 years - this megalithic marvel, with its precise astronomical alignments tracking solstices and shadows, challenges everything we know about human origins, whispering tales of vanished civilizations, possible extraterrestrial architects, and sacred geometries humming with unexplained sound frequencies from the depths below.

As debates rage between those who see an otherworldly observatory amid gold-rich lands and skeptics dismissing it as a mere ancient cattle pen, Adam's Calendar beckons us to question: who - or what - built this timeless timekeeper, and what secrets of our prehistoric past does it guard?
