Eli5: If a compiler is a program that converts your code into binary form for the computer, unless my understanding is incorrect and it isn’t just a program, wouldn’t the compiler also need a compiler to run it since how do you run a program without a compiler?

People can write programs in binary form for the computer without a compiler. This is called machine code. It’s much easier for people to write programs in programming languages, but it is possible for people to write machine code by hand.
The first tools that convert programming languages into machine code were written by people using machine code.
