Thief
Rogue Theologian
None of that takes away from theories being explanations of hard factual evidence. Theories rely very little on imagination and speculation. Sure there may be more questions but the theory still supports observation. There can be wrong theories but very little of it can change, perhaps fine details on exactly how. The best theories, like evolution and general relativity successfully predict outcomes of future experiments and observation. The theory of gravity from newton wasnt wrong just incomplete.
Theory does not support observation.
Theory explains what you are seeing.
The explanation needs to be proven.
