Git makes collaboration much easier because everyone can work in their own copy of the code, create branches freely, and rely on the full history of changes to track or undo work. It keeps development organized and allows multiple people to contribute at the same time without stepping on each other too much. However Git merge does not solve deeper problems. It can combine text but it cannot figure out whether the logic from different developers actually works. When two people edit the same line it creates conflicts and even clean merges can still introduce bugs. This is why communication, testing, and code reviews are necessary.
