Question: What is money?
And something existed before "money" was "created". It was and is called "debt".

Debt is related to property and certainly related to money, since debts are nowadays kept track of in terms of money, but debt is not the precursor to money and certainly debt is not a requirement for a money-based system. It's like saying "before money was created, there were the sun, the moon and the stars".
"and certainly debt is not a requirement for a money-based system." This is kind of true. You could run a trade based economy on pre 1750 level with' lets say gold or silver or sea shells as "money". But you CANT RUN A INDUSTRIAL CAPITALISTIC society without debt. At least nobody has ever been able to show that this is possible. We need growth, we need more energy. I am afraid this will not end well. Read the links I posted in this thread.
Both types of money function in the same way, as a form of payment, but they differ significantly in implementation.
The word you're looking for is "barter", not debt. Debt exists whether or not there is money.
