Hi there! So, the continuity thesis is a big idea that says that things in history change slowly over time, but they don't totally disappear or completely change into something else right away.
Think about it like this: You know how you grow up and change as you get older, but you're still the same person you were when you were a baby? Your personality and who you are as a person might grow and develop, but you're still you. That's kind of like the continuity thesis in history.
So, let's say there was a big change in the way people did things, like how they made food or how they traveled from place to place. The continuity thesis says that, even though things might have changed a lot over time, there were still parts of the old way of doing things that stuck around, even as new ways of doing things came into use.
It's like how we still use some of the same ideas from a long time ago, like the idea of gravity, even though we know a lot more about it now. Or how we still have traditions and celebrations that go back hundreds or even thousands of years, like Thanksgiving or Christmas.
So basically, the continuity thesis is all about how things in history change, but not all at once, and how bits and pieces of the past still stick around even as new ideas and ways of doing things become popular.
