FWIW, your definition of "real money" doesn't comport with the generally accepted notion of "money", at least as I understand it. Gold probably couldn't be used as money in modern society because most vendors probably won't accept gold as payment. Bitcoin might not count as money because its value isn't stable enough. (As far as I know, people have generally given up on the idea of Bitcoin as a currency and instead treat it as a long-term investment.)

AS for the creation of money, it's not just the central bank that creates money. You should read up on fractional reserve banking. It turns out that retail banks do not need to back 100% of their loans with reserves. In the interplay between deposits and loans, this ends up creating money out of "thin air". This is also partly why FDIC insurance exists in the US. In the case of a bank run, the bank literally doesn't have enough reserves to immediately pay out to all the depositors. So the federal government promises to make up the difference.
