[Greek Mythology] How did Cronos know what a horse was?

The first centaur Chiron was conceived when Cronos took the form of a horse and slept with an Oceanid. But Poseidon didn't invent horses until much later.

He just transformed into a random fleshy shape. He wasn't thinking of a specific animal, just some random traits and a big penis. If anything Poseidon ripped him off and took credit.

Or because they're gods, and the fact he's the god of time, it works differently for them than mortals.
