Simulation theory really caught my interest as well. In fact, many masters in history said, "This world is not real." he said. The consistencies in this theory are really intriguing. What we see is not what is actually happening. The perception created by the light reflecting from the substance to our eyes makes us believe that we are seeing it. If we consider the duration of the light to create perception in our brains, what we see means an image from the past. It's a really intriguing subject.
