simulation

I have to admit I got it all wrong in the past. All the arguments that we might be living inside a simulation. The thing is not to explain why we are here or what created the universe. That still wouldn't make any sense.

But the whole point is the so called ancestor simulation scenario. The assumption is that we (or the ones running the simulation to be more exact) at some point reached the point where running such simulation is computationally possible. Assuming the human level curiosity such computational power would eventually be used to run some simulations of the past.
