I actually prefer to reason from what mortals can experience and know, and then a number of questions become impossible to resolve. There is no way for people to tell whether what you describe here or the official story is the truth, except perhaps to ask the few people claiming to have been there before time, and can you really trust them, especially when time wasn't supposed to exist? Similarly, did the gods exist before people and create them, or are the Gods generated through belief and worship? Even if this has an objective answer, it's not like anyone within the world would be able to tell through any experiences.
