I know this is a re post. The question is phrased
better now. Please do not accept if you are not
going to debate.

First I would like to make a simple statement,
that something is something and nothing is
nothing. This statement applies in all fields from
quantum mechanics to the beliefs of a person. To
believe in something is to have “faith” in
something that you’ve heard or come to the
conclusion of yourself; beliefs are “something
believed; an opinion or conviction” Online
dictionary states. Not believing in anything is to
have no opinion on the subject, rather than saying
“no, I don’t believe this, I believe that” someone
who believes nothing will state “I believe nothing
on this subject” meaning they have no opinion on
the subject, and no “faith” of it, thus they do
not believe in anything. Without faith of an
opinion one cannot believe in something, and
because nothing is the opposite of something, the
person doesn’t believe in anything (on that
particular subject).

On an additional note, beliefs are a something
that is “mentally tangible” to the person who
holds them, and someone who doesn’t believe has no
beliefs, and because nothing is “imentally
ntangible” is does not exist, and by that effect
the person has no belief.
