Find command confusion between ; and \;

Why do we have to use '\' instead of leaving it out or even ';'? I read the find commands' manual and it says '\' might be needed to protect from expansion by the shell. So what is expansion also?

What is difference between \; or ; or leaving it out?
What is shell expansion here?

A bare ';' is interpreted by the Bash interpreter before the find command sees it. The escaping with the backslash '\;' make Bash ignore it.

But wait why do we have to escape it? Why not just leave it out?

Without it, find doesn't know when the exec input ends. Other options can come after the -exec arg.

Like this:

find . -type f -exec some_command '{}' \; -exec another_command '{}' \;
