Four possible theories. She was a Leviathan like creature that bread with Dick( First Leviathan) no pun inteaded to make the other Leviathan and then started making here own monsters. (Chances are not that likely.) Second, theory is that she is another type of monster from the same stories that H.P. Lovecraft in the Cthulhu mythos to describe ancient powerful alien beings who come to Earth like the Leviathans. A race called the Old Ones also features in Stephen King's Dark Tower Series. (Chances are higher than first theory.) Third theory, is that God created her to make monsters as Purgatory is the afterlife of monster with souls, and all those souls might keep the Leviathans down. (Chances are higher than first theory, but less than second.) Finally, theory Eve is a deities or a god-like creature that is one of the first other deities after God and Death to appear. It would also explain why she has a small connection to other pagan deities, as said in the Last Season 6 Salute to Supernatural. (Chances are higher than all others in my opinion.) Reason, for the pagan deities with few exceptions are immortal monsterus semi-divine or divine beings as most deities to date appear more like monsters than like how other works show how deities are. Again all theories.
