What Did Humans Do Before Numbers Existed?

You can glance at three cups and know it's three, instantly. But your brain was never born knowing eight. So where did all the other numbers come from? In this video, you'll travel from a baby's crib to 60,000-year-old carved bones, from the Amazon rainforest to the clay tablets of ancient Mesopotamia. You'll discover why your brain can only "see" small numbers, how fingers and notched bones became humanity's first calculators, and why some cultures still live without exact numbers at all. By the end, you'll never look at a clock, or a simple number, the same way again. If this changed how you think about numbers, give it a like, tell us in the comments what number you think humans invented first, and subscribe to Wh-Questions for more surprising answers about the human story.
