This video discusses the innovative ideas and inventions of our ancient ancestors, including a 1,000-year-old copper arrowhead found in Canada, the potential use of machines to build Stonehenge, the history of laundry machines, and the evolution of sundials.

The arrowhead is one of the oldest examples of copper metallurgy found in the region and would have been used by hunters to take down Caribou. The theory of an enormous machine being used to move the massive stones of Stonehenge was proposed by inventor and part-time historian Stephen Tasker, who believes that such machines were referred to in the Bible.

The history of laundry machines dates back to ancient Babylon, where a fully functional washing machine made of a wheel with multiple blades was invented. The article also discusses the evolution of sundials, with the ancient Romans using pocket sundials and Tomas Tukar of Nuremberg being credited with making the world's most beautiful diptych sundials in the 17th century.
