So the past exists forever, it just depends on your vantage point.
Some believe that our experience of time, one moment at a time, is only due to the fact that we cannot percieve the wholeness of time. In that theory, time is not really a series of moments strung together. All time --- past, present and future --- all of them exisit forever, and at the same "time." Time is just another dimension, like the spatial dimensions that we recongnize as space, but for some reason we experience time as a flow and can only percieve it a moment at a time. But in reality it exists in its entirety, just like space does.
