I was under the impression that all Chaos Gods were born via the same process with Slaanesh simply being the youngest, nurgle being the third oldest, and that is further supported by the fact that everything in the warp exists as a result of something that existed in reality.
A race spread and prospers, the density of their psychic energy grows, it creates a chaos god and that god destroys everything like a repeating cycle.
The Warp was created by an advanced psychic civilization The Old Ones who created the Eldar and other xeno races as soldiers in their war against the necrons and at this point the chaos gods did not exist.
