A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not guesses but reliable accounts of the real world. The theory of biological evolution is more than just a theory.. It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact. So the key aspect of theory formulation is the logical grounding of the thesis in established evidence.
