How Does history of philosophy, i guess (history of all ideas) Work?

Imagine history of philosophy is like a big storybook that shows how people have thought and dreamed for thousands of years.

Back in ancient times, there were smart people, like the ones who lived in Greece or China. They asked big questions: What are we made of? Why do we feel happy or sad? How can we be fair to each other? These questions are like the first pages of the storybook, they start a long conversation between thinkers.

As time went on, more people added their ideas. Some thought the world was made of tiny bits, like sand in the beach. Others believed in ghosts or gods. These new ideas are new chapters in the storybook, each one adds a little bit to what we know.

Even now, people still read this storybook and add their own ideas. It's like a big, never-ending game of pass the baton, each person passes on the thinking to the next, helping us understand more about life, the world, and ourselves.
