Ancient Technologies Explained: How They Really Did It (No Aliens)

How did ancient people really move pyramid blocks, predict eclipses with bronze gears, make concrete that keeps cementing itself, fit Inca walls without mortar, and move the giant statues of Rapa Nui? From Merer's 4,500-year-old logbook to X-ray scans of the Antikythera mechanism, a Pompeii building site frozen in AD 79 and a walking moai: what the evidence says, and what archaeologists still debate. No aliens required. Some of this history is hard (forced labour, conquest, slave raids); we tell it without graphic detail. Our sister channel, Stick and Stone Mythology, tells the Greek myths straight from the sources:    / @stickandstonemythology   0:00 Intro 0:47 The Great Pyramid's paperwork 1:51 Wet sand 2:34 The ramp question 3:25 Who built the pyramids 4:50 The Baghdad battery 5:58 A computer from a shipwreck 7:02 What the scans showed 8:09 Archimedes' screw 9:16 Concrete that heals 10:26 Seawater and the Pantheon 11:17 Walls without mortar 12:25 The tired stone 13:32 The heads have bodies 14:40 The statues that walked 16:06 So, who built it?
