Our ancient ancestors were highly inventive, and some of their inventions were so advanced that we still don't fully understand them today. Examples of these inventions include Inuit storytelling maps, snow goggles, the Syum Tunnel, and forced draft shaft furnaces.
The Inuit maps were used by hunters to tell stories of their fishing and hunting experiences, while snow goggles were used to protect against the glare of the sun and snow. The Syum Tunnel was an artificial water tunnel carved in the city of David in the 8th century BCE, and it was most likely built during a time when Jerusalem was anticipating an attack from the Assyrians.
Finally, the forced draft shaft furnaces were wind-powered iron smelting facilities that might have made a significant contribution to South Asia's early mastery of steel production. These inventions demonstrate the ingenuity of our ancient ancestors and their ability to create advanced technologies with limited resources.
