Git is like a super-efficient filing system for computer code. It's a tool that helps programmers keep track of all the changes they make to their code. Imagine you're writing a long story with several friends. You'll want to keep track of who wrote what and when, and sometimes you might want to go back to an earlier version of the story. Git does this for software development. It lets programmers save 'snapshots' of their code at different points in time, which they can go back to if they need to. What's special about Git is that it’s distributed, meaning each programmer has their own complete version of the project. This allows them to work independently and then merge their changes together smoothly. Git is really popular because it makes it easier for teams of programmers to work together without getting their code mixed up, and it helps prevent work from being lost or overwritten.
