Church & Turing, as long as they lived, were fiercely opposed to applying the theory of computation to the brain or physics.
Computation is a tiny fraction of what our human brain does, and is not at all what the brain evolved for.
Is physics computation? No! You fail to see the difference between simulating a mechanism (a model of the world) and the claim that the world *is* a computer. The latter implies that physical mechanisms have symbolic content, which is absurd.

@tyrell_turing@fediscience.org Plus (and that is the argument in my upcoming paper): organisms use their brains to deal with a large world, in which most problems are not formally defined (hence not computable), Before you can solve a problem using computation, you need to formalize it. This is called relevance realization. This process cannot itself be formalized. This is why how we come to know the world is fundamentally different from how algorithms solve problems.
