How 'bout this for debate?
Light from an object hits the retina creating an electro-chemical reaction which reacts on another cell and again on another cell on up the optic nerve until it gets into the brain and we "see." We do not see until then, so we do not see with the eye, but with the brain.
Differing air pressure hits the ear, causing activity in the semicircular canal, which causes an electro-chemical signal to be sent to the brain and we hear. We do not, therefore , hear with the ear, but with the brain.
This sort of activity with our other senses continues in the same way. We taste, feel, smell with our brain.
Conclusion? The whole physical universe is contained within our skulls.
Another conclusion : there is no way to tell if there is anything"out there" at all, because we can only use our senses to tell us if there is or not.
You might also think on the idea that in our dreams at night, time, space, people, rivers, are all created with our mind.
Our eyes detect light. Our brain detects form and color. We see a yellow pencil.
Our ear detects changes in air pressure. Our brain detects sound. We hear music.
Our nerve endings detect pressure. Our brain detects warmth and texture. We feel the touch of a loved one
