> Evolution is a theory
It's an observed phenomena. The mechanisms behind it are in the "theory" category.
> Creationism is a theory
Creationism is no more a theory than "The universe was sneezed out the nose of the Great Green Arkleseizure" is a theory. Creationism is mythology, not theory.
Observations do not constitute a theory. They can only help to validate or invalidate. One of the major observations required to validate evolution is missing. In addition, so is the mathematical evidence. The statistics are simply against it.
That's the first laugh I've had all day! :-)
Observed, hm? Right.
