I don't know what you saw. I do know that for all of recorded history, non-mundane explanations have given way to mundane ones, and I see no reason to think that that pattern will change any time soon. "I don't know" is no reason to jump immediately to the god in the car as an explanation. Are you also one of those creationists who insist that because we don't know what caused the Big Bang, it must have been God?
Have people been drawing pictures of weird **** ever since we learned to draw? Yes, and what does that prove? That people have wild imaginations, that people misinterpret things they see, that people are searching for some graphic way to portray a non-graphic concept ("love," "beauty," "wisdom"), or just that some people don't draw very well. It doesn't prove that people saw "God/god."
Finally, I don't think you know what you saw either. I think that for some reason you have a deep personal investment in having a non-mundane explanation for your experience be the correct explanation, and you are therefore impervious to any possibility to the contrary. You keep insisting that we look at "history" but refuse to see where history leads us - to an understanding that the "magical" explanation eventually yields to the non-magical, prosaic, mundane one.
