A Journey Through Time: From Ape to Algorithm  Thousands of years ago, humans were not the advanced thinkers we are today. We were more like monkeys — climbing trees, hunting for food, and using simple sounds to communicate. But one thing made us different: our brain. Slowly, we began to stand up straight, walk on two legs, and use tools. Our brains became more powerful. We learned to: Make fire,Build homes,Create languages,Paint stories on cave walls.
