What part of the word
plenty do you not understand? Do you really think that picking nits and smearing the messenger is going to remove the vast body of findings that show ill effect? See below for quite a few more references.
The first thing about good science is that you need to have some sort of mechanism to explain your findings. That's what's called a theory.
You utterly misunderstand the scientific method. Experiment and observation are primary. Based on those, hypotheses and later theories can be elaborated in an iterative cycle of experimentation and theory development. But you do not need a theory to perform science: how else but by starting with only initial observations and experiments can you enter a new field of scientific exploration?
Theories can be helpful in interpreting experiments. But it should always be kept in mind that those interpretations are only as good as the theories. And theories are only approximate models of reality: there is always the possibility for them to be erroneous or be improved. If a subsequent observation or experiment falsifies the theory, then both the theory and the interpretations based on it are discarded if the scientific method is followed faithfully. In short, experiment and observation are primary and valuable in and of themselves.
