just a theory 

A phrase often used by science deniers, usually against the scientific theory of evolution. It implies that a "theory" is just an unproven "guess", therefore evolution is an unproved lie. This stems from a fundamental misunderstanding of the word "theory" in the context of science.

In colloquial use, a 'theory' may mean a "guess", but in Science, a 'theory' is defined as "a well-substantiated explanation of an aspect of the natural world." Therefore the phrase "Evolution is just a theory" makes no sense.
A: Evolution is just a theory!
B: Yes, it is. It's a scientific theory that is supported by the best available evidence. Cell theory is a theory too, do you deny that we are made of cells? And gravity is a theory too, do you jump off of bridges?

just a theory 

A pathetic tactic employed by creationists who strive at reminding us the obvious.
Evolutionary biologist: "Observation indicates that we evolved from lower organisms..."

Creationist: "This is just a theory."

Evolutionary biologist: "Of course it's just a theory. Am I expected to be omniscient?"

Personally I think Ness is Sans.

Most commonly used by MatPat, owner of the Game, Food, Film and Style Theory channels.

Used at the end of videos to remind people that he is just making theories and might not correct.
