What does it really mean to be human? I mean a function?
What makes one list a function and the other list just
a list?

That the list begins with certain words like `defun' or
`lambda'. But then quoting that list - what does that mean -
that makes the function-defining functions just data instead?

Actually both defun and lambdas are Lisp macros ...
