What is Money anyway?

[Zeno]

Is there really such a thing as money/currency? Or is it just an idea that everyone believes in, thus making it important? What is money anyway? Does it really exist, or is it just an illusion? These questions are not as silly as they may first appear.

According to the Dictionary of Finance... Money is "legal tender as defined by a government and consisting of currency and coin."

As we all know too well, when governments get involved nothing is as it seems to be. Of course, this may depend on what your definition of is IS.

Does Money, like God, need faith to “exist”?

Can anyone clear this up for me?
