Okay kiddo, so you know how sometimes you like to draw pictures, right? And sometimes you want to make changes to your drawing, like adding more colors or making the shapes look different.
Well, when grown-ups make computer programs, they also want to make changes to their work. But instead of drawing pictures, they write code - which is like instructions for the computer to follow.
And just like your drawings, sometimes the code needs to be changed or updated. But if lots of people are working on the same program, they need a way to keep track of all the changes and make sure they don't accidentally mess things up.
That's where a source code control system comes in! It's like a special tool that helps people keep track of all the changes they make to the program's code - kind of like a time machine for computer instructions!
Whenever someone makes a change to the code, the source code control system saves it and creates a new version of the program called a "commit." This way, everyone can see exactly what changes were made and when they were made. And if someone messes up and makes a mistake, they can easily go back to an earlier version of the code and fix things.
So basically, a source code control system helps grown-ups work together on computer programs without getting confused or messing things up. Pretty cool, huh?
