The process of turning raw ingredients into delicious beer is an extremely complicated one. It involves chemistry, biology, physics, and magic, plus a potentially infinite budget for copper, stainless, and rubber whizbangs. I have only scratched the surface of the possibilities. That is by design.
So, completely neglecting the science involved, and getting to the sequence of events that need to take place to make beer, here is the brewing process in a nutshell.
