It used to be a fact that the Earth was flat. It was not a theory. People positing otherwise were jailed. If it had been just a theory, people would not have been jailed for questioning it. You have now said gravity is a theory, putting it on the same footing as evolution, so that is something. There is quite a body of evidence for both concepts. Yet neither is immutable absolute truth. We don't need them to be. You continue to couch a related set of theories in terms indicating a lack of supporting evidence and to misstate the meaning of science terms as though mere theories are only untested hypotheses. We bristle because in the Midwest it seems not very far from the flat-earth situation all to often these days.
