One hundred percent proof that we live in a simulation, yet zero percent of it matters. The simulation hypothesis proposes that we all live in a simulation. A matrix of sorts. All existence is a simulated reality, very similar to a computer simulation. This simulation may contain minds which are conscious who do not know they live in a simulation. Even the mere suggestion of this fact can send some emotional folks into a headlong tailspin. There is a long philosophical and scientific history to the belief that our reality is a complex illusion. Is it possible Ancient Mystery Schools and other spiritual adepts have known this all along?
