I love how you ignore the primary definition of the word "Theory" -
"1. A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena" - and focus on the
fifth and sixth definitions of the word.
The dictionary doesn't appear to be your friend, after all. Quote mining, on the other hand....
I didn't ignore it, I pointed out the
other parts of the definition.
When there are no facts to refute a theory, the theory is taken as an assumption for the most likely cause of something. When there are facts, the theory, to be scientifically acceptable, must be taught as a theory and it is essential to proper scientific practices to include other explanations.
