That's far from being a "theory" but a phenomenon of science denial.
I call it a theory because that's what it's usually called. For me, this is an expression of science denial. For example, in ultra-conservative religious groups it is not uncommon for people to believe in a flat earth. Or that the earth stands still and everything else revolves around it.

There is a difference between "theory" as some people use it in common language and theory in science. A theory is supposed to be an explanation of a phenomenon and widely supported by observations and/or experiments. mainly, it will have a set of rules to describe best the phenomenon, that are deducted after testing hypothesises (which is what people call theories in daily language, but never really put to a test).
