Multiple parallel realities are created at each moment that the present state has become a past event, but the conception of reality does not allow us to live consciously in more than one plane temporal space ... maybe someday we can go through hidden dimensions or time and space vortex travel between parallel universes, or parallel worlds and consequently global or subjective parallel realities.
The time line is simple we live the present, that becomes in parallel realities and the life purpose is to plan our existential dimension.
Future dont exists as seen thing...
