Why is it customary to put many closing parentheses on one line in Lisp-based languages?

Question

Usually code looks like this:

(one-thing
    (another-thing arg1 (f arg5 r))
    (another-thing arg1 (f arg5 r)))

Why doesn\'t it like this?:

Answer 1

I think a good answer to this is ask a related question:

why don't Python programmers put the glyphs that close nesting on their own lines?

And the answer now is obvious: there are no such glyphs. And it turns out that there are no such glyphs in Lisp either: yes, there are these mildly annoying ( and ) characters that the Lisp reader needs, but human beings do not read Lisp code like this: they read it by indentation and words.
