Actually, by definition, a proposed scientific theory isn't a guess. It might be wrong: But it is based on data, and usually the scientific method. Perhaps data arrived upon by confirmation bias even. But it's still not truly a guess. At worst it's an illinformed decision based on either faulty data or faulty reasoning. But never a guess.
Guess is basically "i think blah blah blah because blah blah blah". An entirely mental construct. Like Intelligent Design.
