They cannot be ideas or not all of them. As season ten states their not Tuplas which is an idea taken form. No ones for sure knows where or when the pagans came into being. Even Lucifer talked to them, like they weren't of Gods work as he couldn't understand them as they always betray their own (kind). I think their just lesser entities that appeared like God but later. And discovered tributes increases their power so build religions around them.
