As our existence is on a four dimensional level, so naturally we see everything as having a start and a finish, i.e. a line on a two dimensional surface.
But there exists situations where there is no start or finish, i.e. a line on a mobius strip. Since we hypothesize that our universe exists on 10 dimensions, we shouldn't assume that our universe's existence has a set start and finish, even though we can only measure back to the big bang.
Fair point, but you can take initiation with regards to a simulation as being whatever confluence of events is triggered by something external to the universe to cause the universe/simulation to exist.
Point being is that by definition, a simulation has to simulate something, and therefore needs to exist sometime after the thing it is simulating.
