is an example of a THEORY. THEORIES can be proven wrong, not facts. I just pulled out my Webster's and here is the definition for a fact: "Something that actually exists or has actually occurred; something known by observation or experience to be true or real: a scientific fact."
Here is the definition for theory: "a plan or scheme existing in the mind only; a speculative or conjectural view of something."
Hmmmmm, sounds to me like you have a THEORY that doesn't stand up to the FACT. Debate that.
