That's not a fleshed out argument. Why do you believe that "statistical combinations" can't create novel ideas?
It's like saying a calculator could spontaneously derive its own proof. No it can't, because it has no ability to do that. It physically does not have a way to create new ideas. It cannot reshape its own circuitry like a brain and it does not have spontaneous thoughts.
What makes an idea "novel"? What types of physical processes can create new ideas or have spontaneous thoughts, and which can't? What is "special" about brains, in your view?
I'm looking for some meat on the bone here.
