Proof of the soul?

But let's play philosopher for a moment.

Let's say I start simulation on my computer. A virtual environment with artificial lifeforms. Like this one:
http://www.swimbots.com/
But then I go to another room. I have no idea what is going on in this simulation. I don't know if something is still alive there, or if everything just died. Maybe my computer crashed and this simulation is no longer running. Nobody knows what's going on there.

Now let's say there is no soul. We are our bodies. Our thoughts are just chemical reactions in our brains and there's nothing after death.
Wouldn't such a universe be like this simulation?
Wouldn't it run by itself without anybody knowing what's going on in there? How am I different from a swimbot in this model? Does the fact that I can observe what's going on imply that there is something more, some external observer that we could call a soul?

I can see through the eyes of this body. I can hear through those ears. If those were just biological processes and nothing more, nobody would observe that, would they? If I was just a swimbot and there was no God, nobody would even know, that this universe exists, would they?

The universe would be like a simulation run in another room.

Is it enough to be proof that there is something like a soul?

Of course, me being able to observe this universe can work as proof only for me. For you, I am just some letters on the screen. It can't prove anything, because as far as you know, I could be a completely unaware, unconscious thing with a script to tell others that it can see through its own eyes.
You need to be able to observe for yourself in order to consider it proof that there must be something more. Your experience can be proof that you have a soul.

What if a zombie read this text? Or a bot?
Would they analyze this text thinking they can understand it when in reality there is no one there to actually experience anything?


PS
Are swimbots self-aware? Do they know they exist?
Why do I see through "my" eyes and not through anybody else's?
Is everything self-aware?
What if humans are the only things in the universe that believe that there is no such thing as a soul?

I would like to apologize for writing this post to anyone who has read it. I'm sorry, it won't happen again.
