We don't experience the sun going up and down, we experience its direction changing relative to the horizontal plane, and it is not an illusion: it matches planetary motion. The mistake arises when interpreting the raw experience. Sensations don't lie. Another example: Metal feels colder than plastic, but the sensation is right again: you are loosing more heat when touching metal.

But the sensation in a sense is a lie. Cold strictly speaking isn't real. And for much of human existence we spoke of it as if it was a substance due exactly to this specific sensatation.

Even so, the "quality" of an experience could be regarded as an interpretation of sensations.

And to add to this, sensations do lie. We hear voices that aren't there, things feel hot when they're cold, we feel stationary when we're hurtling around the sun at high speed. Our bodies are not built to sense the truth of the world, only to survive in it. Sometimes those things coincide, sometimes not.
