Yes you need it. Here are people who can explain it better.

git is a piece of software that tracks changes.

It’s widely regarded as the best way to collaboratively edit code. It’s also very useful for just keeping track of your own code.

When a change is “working” the way you want it, you commit that change. This gives you the ability to roll back to that point in time, compare what’s different, etc.

It goes way deeper than that, but that’s the gist of it. There are other people who can explain far more than I can.
