What evidence is there that physics is 'compressible' rather than simply 'uncertain'?

Belief that consciousness is somehow more fundamental than 'brain physiology' is essentially a kind of solipsism and is completely unfounded in facts or experiments.
If we're in a sim, it's Physics rules that are being "run" and the existence of brains is purely emergent.
