Why Git? Also what is Git?

Git is a tool used for managing the files of repos.

This is what is known as a Version Control System(VCS). Unlike a most tools that save the progress, where the last save overwrite the previous version, a VCS will save a snapshot of where the project is at its current state and can be reverted back to a previous state if needed.

Each saved version is called a commit.
You may decide to commit after completing a single function or an entire feature.
Commits show the evolution & growth of a project.

What is a repository?

Repository (or repo): a repository is where the history and different versions of a project are stored. Developers use repositories to collaborate on software projects, tracking changes, resolving conflicts, and maintaining different versions of the codebase.

Github: What is it & why use it?

Github is an online platform for hosting Git projects.

Sharing: Public repositories can be viewed, commented on, and downloaded by other members of the Github community
Collaborating: Developers can contribute new code to repositories, get feedback on their additions, and eventually merge new changes.
