Ok. I'm now a god.
I create a universe that lasts many billion years. I set everything up so that life will happen as I want it in this universe with the rules, otherwise known as laws of physics, that I have set up. And I pop some godly cosmic popcorn to watch the show.
Several billion years later, one of my planets starts to show signs of life, which gradually progress over a few more billion years. Eventually, they reach bipedal, sentient organisms on this one planet in a vast cosmos. And I decide I want to tell them about myself and my role and their role in the universe.
So far, so good right?
However, when I decide to reveal myself to these people, they are primitive, and don't have the foundation to understand most of what I would tell them about the makeup of the universe. So, what would I do? Well, I would tell them about myself and what I had done and where they fit in in a way they could understand.
Or, perhaps I decide to hold off till they have an advanced understanding of the universe. Then I would still talk to them in language they understand. But, if they are capable of understanding advanced science and whatnot, then I talk to them about that.
So, the amount I reveal about the workings of the universe is what they can cope with. If they can only really cope with simplified ideas because they really can't comprehend billions of years or space so vast when they don't even know a fraction of the size of their own planet, I talk to them in simplified ideas. Then I can tell them about me instead of about things they really can't understand. Likewise, if they have some idea about the way things work, then I tell them at that level. If they know about spacetime, I include spacetime in my revelations. If they don't really get much beyond a few generations, I don't include billions of years in my revelations.
I would also make sure that my revelations should be obvious to future generations as more myths or allegory than literal truth. And I would make sure I don't make my revelations and the real world contradict each other when read as they should be.

But that's just me.
