I believe in other versions out of Chaos came the three you mentioned but also nyx and erubus and sometime Chronos and Ankha (or some other spelling of it). I believe some stories states that Nyx was the oldest fallow by Gaea and the rest. Also some versions of this story doesn't even mention the primordial Eros
Yeah, there are a ton of variations of the actual myth. It’s crazy to think that we don’t even know if the information we have is accurate at all to the original story.
