How can Git save my life?

i think our life is easier without git haha i think with git we have another way to handle with computer and it is good and we can create project and push it in github and that make every thing in the projects it easy to handle with Thinking......... and i think when the computer performance is not good we can use git to handle with the computer and i think git make warmup better than send to sahar because when we return and time in github  but i need more practice in git and github because it is the first time i used git so  I Think that is it for today thank you very much
