The modern conception of money is that something is the a good of exchange and a good of account. I would argue both of those have been invented independently both in various decentralized ways and by a state.
You can also keep accounts in your head. The concept stays the same if you write it down or not.
If the notes you are circulation are IOUs for that good then that does not change the underlying concept.

Markets come about as soon as you have property rights. Property rights come about in many ways (I have other comments in this thread making this point).
When you of course go impose a property rights solution on a society then that is of course a form of central planning.
So I would say again, you can have both, you can central plan a market, but not all markets are centrally planed.
Frankly all of them seems to be invented privately, and then gets backed by the state as a last resort when private parties gets into a dispute and risk taking a large part of the economy down with them.
And apparently the notion of debt exited long before the notion of money. And even afterwards money was something used between individuals that didn't know each other (different tribes effectively).
Some think that money in the form of shells existed back to at least 75,000 B.P.[1]. Language and controlled fire arose around the same time. Money (easily transferable anonymous debt) may have been used by (proto?)humans before the notion of words. Money may have been one of the few keys to the rise of human dominance.
