Simulation Theory

For starters, I don't believe in Simulation Theory.

Do you know about this? It's the scientific/philosophical theory that our entire universe- everything- is just a simulation of reality, like the Matrix. Yes, people actually believe this. Some think our universe is just a hologram of itself. Some people think super-intelligent aliens are simulating this reality. It's a little more scientific than that, I think, but from my understanding, that's basically what some people, including scientists, believe.

I haven't really done enough research into the science of it to refute that. I basically object to Simulation Theory on one philosophical ground: in order for something to be a simulation, it has to be a simulation of something.

Imagine for example that you use a computer to simulate a chair. What's different about the computer chair from a real one? Well, the computer chair is a bunch of electrons making a screen light up in a way that corresponds with mathematical points calculated by the computer. Also, you can't sit in it. So far so good?
Now imagine you wanted to simulate a chair with wood. What do you do? You make a chair. Once you simulate something closely enough, you aren't simulating it anymore. You're creating it.

So the simple question is: if our universe is a simulation, what is it simulating?
And one possible simple answer goes "a universe with our specific laws of physics." The theory goes (I think) that the "real" universe outside the simulation doesn't correspond to the laws inside here. Or maybe the history is different. Or something.
But the point remains: if all it's simulating is itself, at what point does the simulation stop being a simulation and start just being reality?

However, there is something deeper I want to point out here. Where does the idea of Simulation Theory come from? Why is it such a fascinating idea? Like most world views, I think there is a hint of truth in it.
This world is a simulation. But not of itself.

This universe is a simulation of Heaven.
Earth is an old video game. It's a low resolution Atari game compared to reality- that is- compared to Heaven.

Earth is a massively multiplayer sandbox game where souls from Heaven and Hell can meet, interact, and talk with each other for one brief moment in Eternity. Just like how here on Earth, our massively multiplayer online games allow two different people from other sides of the world- from different backgrounds and countries- to connect in ways they never could otherwise. That's part of why its so important to stay here while we can. Don't worry, Heaven isn't going anywhere.

We are in a simulation, and one day we are going to wake up. See you out there.
