The past is the past. End of story.
But that does not mean that the past isn't happening now?
It stands to reason if the past is going along at the same clip as the present is, doesn't that mean that the future is also?
So by that reasoning, the past, the present and future are happening at the same time, but not as we percieve it with our earthly selves.
That is why angels never grow old, because there always in the realm of now.. Outside of time, as we percieve it.
By that rational, the earth is just being formed, the big just went bang, and the end of the world is happening, in the biblical sense of course; or as I percieve it.
This is why, we are now in this current body to percieve with these senses that we wouldn't ordinarly be able.
So its like we're little children sent out to play, and here we are playing with our lives, learning and experiencing, and when playtimes over, we go back to god/great spirit (or whatever name we wish to call on) and tell our stories of how we played.
What fun.
