So, I just was trying to convince you that you are stuck in a world of perceptual experiences (consciousness) rather than what is known as the physical world.
This fact alone does not establish that there can not be a physical world that generates the consciousness experiences.
In this hypothesis known as physicalism or materialism, the world you see is fully accounted for by the entities described in modern physics: atoms, particles, fields, waves, etc. The neuronal networks in the brain, under this hypothesis, fire according to special dynamics and consciousness is produced.
That is the physical or material hypothesis of the world: there is an abstract world with its own independent existence outside of both of our perceptions, and the abstract brain (also composed of fundamental physical entities) fires according to complex dynamics as to generate consciousness:

This story has one issue: It can't explain consciousness, which is the only thing you can know for certain exists. This is known as the Hard Problem of Consciousness in philosophy of mind. In fact, this hypothesis can't account for a single conscious experience to date.

How does physicalism account for the taste of chocolate? No answer. How about the feeling
of a stomach ache? It has nothing to say. How about the experience of the color blue? It can't account for it.
Physicalism - for the last 100 years - has not accounted for a single conscious experience. This is a remarkable failure. It is has to do with the fact that abstractions have nothing to do with experiences; there is a fundamental gap between something that is not a consciousness experience and conscious experiences.
In a sense, particles, fields, waves, etc (all the entities proposed in modern physics) are abstractions that have nothing to do with experiences. So when we try to explain consciousness in terms of these abstractions, we inevitably fail.
It is like trying to pull the landscape from a map of the landscape. You'd look insane trying to do that, but when it comes to physicalism, this is somehow acceptable, rigorous discourse.
