Your argument is missing the whole concept of emergence, which is what is at question here. How does emergence come about, under what circumstances, and what is possible in those circumstance? It's an open question.
Following your logic, one could argue that physics is basic and follows well understood rules. We can do some fancy math to predict what will happen in a given particle interaction. How would these basic particles ever give rise to life and minds with reasoning ability?
Well you and I are an existence proof that basic rules when followed on massive systems can give rise to emergent behavior.
