There is a simple reason why science has a very naive understanding of ourselves and our universe. It can only discover correlations, not causation. It does not have a concept of quantum measurements. It has no tools to measure quantum fields. Since everything in the universe happens at a quantum level, science as we know it is only able to breach concepts originating from how relationships function at a rudimentary level, but not why those relationships exist. Science and its conclusions are one-dimensional and there lies its greatest limitation and ignorance, and thus it will never supersede what humans already know about themselves.
Science is so far behind simple empirical observation, so far behind the actual functioning of the human body, so far behind anything remotely relating to the understanding of ourselves and our universe because it can’t assess the subatomic forces that guide all matter. Science can’t even measure a quantum field or the functioning of more than 90% of our DNA and yet we expect it to be able to determine what a cure is? It is not conceptual so it can’t.
