Theory

It's just (Only) a theory. Yeah, right. So is gravity.  Creationists use that phrase or something similar  with amazing regularity. And just as often, I wonder are they really that ignorant? Or just blind with fear?

In science a theory is NOT a guess. It's NOT a hypothesis. 

Nothing can be done about the blindness I suppose. However, in the interest of correcting the ignorance I present the following;
