The real answer is this... You are being actively deceived. Mankind is being held in an immersive, persistent, photorealistic simulation of physical reality.

In order for you to see the illusion yourself, then you would need to see the physical world change before your eyes, like the image on a computer screen. Well, I can see these changes all the time.

The truth has nothing to do with dual or non-dual teachings. The fact is humans are not the top of the food chain. That's why you can't see the illusion.
