This has been on my mind for the last little while.
Having read a few books on simulation theory and considering the work of people like:
Robert Monroe & Tom Campbell on OBE’s,
Dr. Ian Stevenson, Dr. Jeffrey Long, Dr. Brian Weiss, Dolores Cannon among others on past life experiences, reincarnation, NDE’s, and SDE’s
It appears that as much as we experience everything as ‘solid’, we seem to be within a multi-dimensional simulation.
From that perspective, the whole idea of the ‘big bang’ makes sense as the start of this particular simulation that has been in operation for about 13 billion years, when the ‘program’ was ‘executed’.
So, from that point of view, what or who are we, other sentient beings and all ‘material’ in the uni/multi-verse?
